wavelength and energy
hi all!
I just wanted to clarify this, but shorter wavelengths mean greater energy right? And then since wavelength and frequency are inversely related, short wavelength means high freqeuncy so can we assume that high frequency light always has a high energy?
thank you!

Re: wavelength and energy
Hi! Yes, you're right, shorter wavelengths have higher energy and shorter wavelengths have higher frequency (because more waves pass a given point in certain amount of time). Therefore, high frequency light has high energy because amount of energy is directly proportionally to its frequency.

Re: wavelength and energy
Yes! Shorter wavelengths have a higher amount of energy because they occur more frequently (high frequency).
Re: wavelength and energy
That's right! Shorter wavelengths means higher frequency, and frequency is directionally proportional to energy with a proportionality constant of Planck's constant. So, high frequency also means high energy.

Re: wavelength and energy
You are correct, shorter wavelengths correspond to higher frequencies. In the formula E=hv (where v is frequency), we can see that a greater frequency will result in a higher energy.

Re: wavelength and energy
Hi!
Yes you are correct! Since wavelength and energy are inversely proportioned (E=hc/lambda), an increase in wavelength causes a decrease in energy.

Re: wavelength and energy
Yes, yes, and yes. Remember that energy is a quantized amount, it has discrete values, but frequency and wavelength can change. By change I mean that the values will change, but when you multiply frequency times wavelength the product will give you the speed of light constant, known as c=(lambda)(frequency)

Re: wavelength and energy
Hey! Great question, so about the relationship about wavelengths and energy I like to remember it like this: higher energy is due to higher frequency of waves, in turn wavelengths are considered shorter. If wavelengths are longer that means that there is lower energy due to decreased frequency of waves.
I have included a website of how wavelength and energy relate to each other: https://www.e-education.psu.edu/meteo300/node/682

Re: wavelength and energy
Yes, you are correct! Shorter wavelengths correlate to a higher frequency and higher energy and vice versa for longer wavelengths.

Re: wavelength and energy
Yes! Shorter wavelengths have higher energy because they have a higher frequency.

Re: wavelength and energy
There is an inverse relationship between wavelength and frequency. In other words as frequency increases, the wavelength will decrease. The energy also increases when there is a shorter wavelength and higher frequency.

Re: wavelength and energy
Yes! The shorter the wave length, the higher the frequency is, meaning high energy. The longer the wave length, the lower the frequency, meaning low energy.

Re: wavelength and energy
Yes, from the equation c=lambda* v, we can tell the wavelength and frequency are inversely related. We also know that energy and frequency are directly correlated. Therefore, everything you stated in valid.

Re: wavelength and energy
Yes! Right on the money! Because of C=Lambda*Frequency, when wavelength decreases, frequency increases. Because of E=hv, the greater the frequency, the greater the energy of a photon.

Re: wavelength and energy
Yes! Shorter wavelengths means greater energy because with the equation E = h * c / lamda, since lamda is the denominator, a larger value in the denominator indicates that the result would be smaller. Therefore, with a greater wavelength there is less energy and vice versa. As for high frequency, you are correct in that it also has high energy because if we consider E = h * v where v is frequency, then we can see that frequency and energy is directly proportional.

Re: wavelength and energy
Everything you stated is correct, also keep in mind the equation C= Lambda x V. Wavelength and frequency are inversely proportional. In other words, as wavelength increases, frequency decreases and vice versa!

Re: wavelength and energy
Hi!
Yes! Shorter wavelength means higher frequency and more energy. The thought process I go through for this concept is I imagine an oscillating graph (sin or cos) and the more frequent one cycle occurs the shorter each space between the cycle is and the higher energy.
Hope this helps.
