How Fast does this travel?

A red light has a speed of 3.0 x 10^8, is a green light faster or slower?

light travles at a constant speed. so they tried to trick you ;)

I'm pretty sure all light travels at the same speed. At least thats what my teacher Mr. Faucherr told me.

3.0 x 10^8 is the speed of light in a vaccum. This is absolute, and the same for all wavelengths of light.

Both of them travel at the same speed. They are however different in wavelength and frequency.

A legitimate question is:

Q: Which light has more energy, red or green?
A: The answer would be green, as it has a higher frequency.

Speed = wavelength x frequency

Speed of light or any other form of electromagnetic waves is always the same, regardless of frequency. Since the speed is always the same, higher frequency means shorter wavelength, and vice versa.
