Question

Is velocity of photons independent of frequency?

Answer 1

Velocity of photons in Independent. 

By Special Relativity, the velocity of light is constant at ~ 3 * 10^8 m/s for all observers. 

The equation for all waves is: 

Velocity = frequency * wavelength 

For light: 

3 * 10^8 = f * wl 

change wavelength and frequency also changes so that the velocity remains constant.
