That explains the velocity of light, reflection, refraction and so on.

Time for a lesson on the electromagnetic spectrum, Sesame.
The lowest radio waves start and 10^3 hertz. Lower frequencies are referred to as voice frequencies. Microwaves start at just below 10^9 hertz and go to just below 10^12 hertz. Visible light is just below 10^15 hertz. In between microwaves and visible light is infrared. The rest I will agree with you.
