I know that frequency has an indirect relationship with frequency, meaning that if frequency starts to increase, the wavelength will subsequently begin to decrease, and vise versa. Also important to note is that the greater the frequency, the shorter the wavelength will be.

Wavelength (nm) is the length of a full wave while the frequency (s^-1) is the how often the wave occurs in a period of time (its speed). They are inversely proportional to each other.

Wavelength and frequency are inversely proportional, meaning as one decreases the other increases, and vice versa. A wave with a large frequency has a small wavelength, and same the other way around. Definitively, the wavelength is is the distance between a point and that same point in the next cycle of wave. The frequency is the number of times a point on a wave passes through another point in a certain period of time (ex: per second).

Wavelength is defined as the distance between two adjacent crests of a wave, and its unit is meters. Frequency is defined as the number of wavelengths that pass a given point in one second, and its unit is Hertz. As given by the equation (), the wavelength and frequency of any wave (including light) are inversely related.

For light specifically, as wavelength increases, both the frequency and energy of each photon of light decrease. As the wavelength decreases, both the frequency and energy of each photon of light increase. The energy of a photon of light is directly proportional to its frequency, as given by ().

Hopefully this helps, and please correct me if there are any mistakes.

Wavelength is the length of a wave between two peaks/troughs and has an SI unit of meters (m). The symbol λ (lambda) is used to denote wavelength.
Frequency is the number of cycles (wavelengths) of the wave that passes in one second, and has a unit of s-1 (1/second), also known as Hertz (Hz).

Wavelength is inversely proportional to frequency. That means that the longer the wavelength, the lower the frequency, and vice versa.

Hi!
A wavelength is basically the distance between one peak to another. Usually all waves are characterized by wavelength, amplitude, frequency and speed. Frequency is the number of times per second that a wave travels through a cycle. It's measured in Hertz (Hz) and represented usually by the letter f in equations. The relationship that wavelength and frequency have is that they are the inverse of each other. Like longer wavelengths have lower frequencies and shorter wavelengths have higher frequencies.

Shorter wavelength = higher frequency = higher energy

A wavelength is essentially the distance/length of a wave while the frequency is describes the amount of times the wave occurs. So they are inversely proportional, if the wavelength is great the the frequency is small. Whereas if the frequency is great the wavelength is short.

Wavelength and frequency are inversely proportional. Wavelength is the length of a wave from peak to peak or trough to trough and frequency is the number of waves completed in a given period of time.

The wavelength measures the peak to peak distance of two waves while frequency measures how often a complete cycle occurs within a second. For wavelength, the word length can help you think of how long the wave is (a higher wavelength means longer waves while lower wavelength means shorter waves).
For frequency, you can think of the word "frequent" relating to how frequent the wave will occur in a second. The higher the frequency, the more waves per second. The lower the frequency, the less waves per second.
Frequency is measured in s^-1 and wavelength is measured in meters (distance).

Hi Kimberly,

Wavelength is defined as the distance between two crests or troughs of a full wave, and the SI units for wavelength is usually nanometers. On the other hand, frequency is how often the wave occurs in a period time, calculated in seconds. The two are inversely proportional to each other. This means that as the frequency increases, the wavelength decreases, and vice versa.

Wavelength and frequency multiplied will always equal to the speed of light (c), meaning that they are inverses of each other. As such, when wavelength increases (how wide the wave is), frequency decreases (how many waves cross a point in a given amount of time), and vice versa.

Wavelength is the length of a wave (often measured from peak to peak on a graph, in nm). Frequency is the speed of the wave, aka how many waves pass in a certain amount of time. The relationship between wavelength and frequency is wavelength x frequency = the speed of light.

Hello! Wavelength and frequency are inversely proportional to each other. Wavelength is the distance between any two points and the frequency is the number of waves passes a certain period of time. As wavelength increases, the frequency of the photon light will decrease. Similarly, wavelength decreasing will result in the frequency to increase.

They have an inverse relationship so when frequency increases then wavelength decreases.

Wavelength is the distance of one "wave" (can be visualized as the distance between peaks), whereas frequency is the number of these waves that pass a point in an allotted time.

Wavelength is basically the distance between one peak of a wave and the next wave, frequency is how often the waves occur within a specific time period. Additionally wavelength and frequency are inversely proportional because as wavelength increases, frequency decrease and vice versa.

Wavelength is the peak to peak distance between two waves. It can also be measured trough to trough (whatever way it is easier to visualize). Frequency is the number of time a point in the waves passes a checkpoint in a certain allotted amount of time. The units for wavelength are usually meters to nanometers. The units for frequency is Hz, or 1/s.
The frequency and wavelength of a specific wave are related because the wavelength is inversely proportional to frequency of the wave.

Frequency and wavelength are inversely proportional to each other. The wave with the greatest frequency has the shortest wavelength. Twice the frequency means one-half the wavelength. For this reason, the wavelength ratio is the inverse of the frequency ratio.

Hi! Like everyone above said, wavelength would be the distance from peak to peak or trough to trough of a wave, and this would be represented by the Greek letter, lamda, in wavelength calculations. Frequency, on the other hand, is the number of cycles a wave goes through in a certain amount of time, usually measured in a second. These two values are inversely proportional, so that when wavelength increases, frequency will decrease and vice versa. Hope this helps :)

Wavelength and frequency are inversely proportional. The higher the frequency, the shorter the wavelength. The lower the frequency, the longer the wavelength. Wavelength is measured in nm (nanometers). Frequency is measured in Hz (hertz, or cycles per second. Sometimes this last part can be seen as s^-1). Also, both frequency and wavelength are unaffected by the speed of the wave.

I remember learning that wavelength and frequency are inversely proportional, meaning that as one increases, the other decreases. Frequency and wavelength of the wave get multiplied together to get the speed of light, which always equals 3x10^8 m/s. Therefore, as one increases, the other must decrease to equal the speed of light. Frequency shows the number of oscillations of the wave in a given amount of time, whereas wavelength measures the distance between two points, the peaks, of the wave.

Wavelength is a measurement of a wave from a peak to peak in meters. While frequency, you could think of it as a rate of how much waves passes through a specific point in time per second (s^-1).

The wave length of a wave is the distance between each crest of the wave and is inversely proportional to the frequency. The frequency would be the amount of periods of that wave that would move in a certain amount of time.

In a period of time, a wave occurs a certain number of times. This is called frequency. The length of a full wave is the wavelength.

They have are inversely proportional to one another. The wave with the highest frequency has the shortest wave length and vice versa.

The relationship between wavelength and frequency is represented in the equation c=lambda*v

As wavelength increases, frequency decreases and vice versa. A wavelength of a wave is the distance from peak to peak or trough to trough. Frequency is the amount of cycles per second for each wave.

Wavelength is the distance between wave crests and frequency is just how many times the wave passes through in a specific time. They are inversely proportional and that relationship can be modeled by c= lamda/frequency.

Wavelength is the distance between the two peaks (or troughs) of a wave. The frequency is how many cycles the wave goes through in one second. They are inversely proportional meaning that the higher the frequency the lower the wavelength and vise versa. This is because if the wavelength is longer that means the wave goes through less cycles if the period of time (1 sec) remains the same.

Like everyone else has mentioned, there is an inverse relationship between wavelength and frequency. A good way to remember this is to think of the equation e = hv which is also equal to hc/λ (where h is Planck's constant, v is frequency, λ is wavelength, and c is the speed of light). Setting hv = hc/λ, you find that c = v*λ or speed of light equals frequency times wavelength. It is from HERE that we derive the idea that as frequency increases, wavelength decreases (becomes shorter), and vice versa!

I hope this conceptually makes a lot more sense than just trying to memorize "frequency goes up, wavelength goes down" and so forth!

Wavelength is the distance between peaks (the peak to peak distance). Frequency on the other hand is the number of waves that occur within a second. For this reason, wavelength and frequency have an inverse relationship. For example, if the wavelength is large, the frequency will be smaller because fewer waves will be able to occur within a single second as compared to waves with a smaller wavelength.

Wavelength is the length of 1 full wave, from peak to peak, trough to trough, or every other node. Frequency is the number of cycles per second. They both are inversely proportional and related through the equation c=v*lambda.

Wavelength and frequency are inversely proportional. Wavelength is the distance between two peaks/troughs in a given wave, and frequency is how often those peaks/troughs occur in a given unit of time (I believe it is generally 1 second). This means that if the distance between two peaks or troughs is shorter, they will occur more times in one second, meaning shorter wavelengths = higher frequencies and vice versa.

Wavelength and frequency are inversely related, meaning when one increases, the other has to decrease.

I think of it like this-- wavelength is the space between two peaks, and frequency is how frequently those peaks occur.

If a wavelength is higher (there is more space between two peaks), then the number of peaks within a certain distance has to decrease (frequency decreases).

If a wavelength is lower (less space between peaks), there has to be [relatively] more peaks within the same certain distance (increase in frequency).

Frequency and wavelength are inversely proportional, so when frequency increases, wavelength begins to decrease (vice versa). Wavelength is measured in meters or nm and describes the distance between 2 neighboring peaks of a wave. Frequency is in Hz or 1/second and addresses the number of cycles/wavelengths. A higher frequency equates to a shorter wavelength.

Wavelength is the distance between two peaks and frequency is the amount of waves per second, or hertz (Hz). They are inversely proportional, so if one goes up the other goes down.

Wavelength and frequency are inversely related. For instance, a wavelength with a higher number of (nm) will have a smaller frequency than that of a wavelength which has a lower number of (nm). This wavelength will have a larger frequency!

Wavelength and Frequency are inversely related. The longer the wavelength means lower frequency and energy. The shorter the wavelength, the higher the frequency and energy.
