I am trying to find out, what is the affects the velocity of the light wave projected by the laser? I am going to ITT tech and this is a very diffucult thing to try and find on the web. I have been searching for over an hour trying to find the answer. I would really appreciate the help.

Light tends to travel at the speed of light particular to the medium it is travelling in.

Unless I've missed something, perhaps you need to rephrase your question?

It says: Execute the necessary research to determine whether the color of a laser affects the velocity of the light wave projected by the laser.

Do you know what the difference is between, say, a red light wave, and a green light wave?

Yes you have. The speed of light is a constant in a vacuum.

What are the optical properties of air and how might they effect the speed of light as a function of wavelength ?

Sorry, mis-placed comma.
