Re: wavelength
Speed remains the same. It is always the speed of light, which is 2.998x10^8m/s. Frequency changes with wavelength. As wavelength decreases, frequency increases.

Re: wavelength
If you are referring to DeBroglie's wavelength, since speed is in the denominator, when speed increases, wavelength decreases and vice versa.

Re: wavelength
The speed of light is constant so only frequency changes with wavelength (inversely). In terms of the de broglie equation, the velocity is inversely proportional to the wavelength.

Re: wavelength
Regarding light, wavelength does not affect speed since the speed of light=c=2.998*108. With De Broglie's Wavelength, since velocity is in the denominator, we know wavelength and velocity have an inversely proportional relationship. This means when wavelength increases, speed decreases.

Re: wavelength
Speed should always remain constant so it should not be affected by the length of a wavelength.
Re: wavelength
The speed of any EM radiation is constant at the speed of light (2.998x10^8 m/s). If you're referring to the frequency of a wave: as the wavelength of a wave increases, its frequency decreases.

Re: wavelength
Speed should not be affected by changes in wavelength, unless you are talking about the velocity in De Broglie's equation: lambda = h/mv. In this case, wavelength is inversely related to velocity so increase in velocity would mean there is a decrease in wavelength.

Re: wavelength
Hi!
If you are using De broglie's equation, Considering λ=h/mv, as velocity increases, λ decreases. Hope this helps!

Speed does not change with wavelength since speed is a constant: c=2.99792 x 10^8 m/s.

Re: wavelength
Speed of light is a constant c. But if you are referring to the velocity for an electron, that can change based on wavelength.

Re: wavelength
Hello,
If you're referring to the speed of light, speed does not increase or decrease as it's a constant (c = 2.998 x 10^8). If you're referring to De Broglie's equation (λ = h/mv), the velocity (mv) is inversely proportional to the wavelength (λ). This means that if velocity increases, wavelength decreases, and vice versa.

Re: wavelength
Wavelength and frequency will either increase or decrease to keep the speed of light constant, at 3*10^8 m/s. So what this means, is that if wavelength increases, frequency will decrease by the same proportion to keep the speed of light constant. Frequency would change, speed of light would not.
Re: wavelength
All electromagnetic radiation travels at the speed of light, so speed is constant. However, in the de Broglie's wavelength, when wavelength increases, velocity decreases because wavelength and velocity are inversely proportional.

Re: wavelength
in terms of light, speed is always the constant 3 x 10^8 m/s.
As wavelength increases though, the frequency of the electromagnetic wave decreases. (The number of wave cycles per second decreases)

Re: wavelength
Speed always remains the same. Different wavelengths will have different levels of energy (the smaller the wavelength the more energy).
Re: wavelength
c = wavelength * frequency
speed is always constant (3* 10^8) --> speed of light.
Wavelength varies inversely based on frequency- the lower the frequency, the greater the wavelength and vice-versa.

Re: wavelength
The speed of light is always the same, so there's never any change. Changing the wavelength won't make it any faster.

Re: wavelength
If you're talking about De Broglie's equation, then yes as velocity increases then wavelength decreases and vice versa. However, if you are referring to speed as a constant then it should not be affected.

Re: wavelength
Hello,
Because the speed of light is constant, the speed does not increase nor decrease with wavelength. But it is crucial to know that energy is associated with the size of a wavelength.

Re: wavelength
When you look at the equation for wavelength, you will see that there is a constant c, which is speed of light. That is the speed and it does not increase or decrease with wavelength.

Re: wavelength
Hi,
I believe speed would remain the same even though the wavelength changes. When the wavelength changes, the frequency would only change since the speed is constant. Thus, the speed would not be affected by the wavelength change.

Usually speed of light is constant as wavelength changes but I believe the frequency changes

Re: wavelength
Sometimes, it helps me to remember conceptual topics through formulas and equations we are given. In this case, we are given c=lamba(v) as an equation on our equation sheet, and we are given that c = 2.998*10^8. Thus, even if you don't remember if the speed of light stays constant during a test, you can quickly glance over to your equation sheet and confirm that the speed of light is indeed a constant, no matter wavelength or frequency.

Hi!
No. Speed of light is constant. The value of this constant is c = 2.998 x 10^8 m/s.

Re: wavelength
Nope! Speed does not increase with wavelength, just as the frequency of electromagnetic radiation also does not determine the speed. The speed of light is constant and that is why the frequency of a wave is inversely proportional to the wavelength.

Re: wavelength
The speed of light is a constant number, c = 2.998x10^8 m/s, so its value is not affected when wavelength is increased or decreased.

Re: wavelength
If you're talking about (c=hv), c (the speed of light) remains constant and it is the wavelength and frequency that fluctuate inversely.

Re: wavelength
Since speed remains the same (c which is the speed of light), frequency and wavelength are dependent on one another. An increase in wavelength leads to a decrease in frequency and vice versa.

Re: wavelength
Speed remains constant, this is shown by the equation c=hv. Remember that speed is a constant, c = 2.998 x 10^8 m/s to be exact. However, frequency changes with wavelength and is inversely proportional as well. So as the wavelength decreases, the frequency increases.
