All electromagnetic waves travel with the same velocity in a vacuum. Which is at the speed of light. This has 7 different types of frequencies. Beginning at the lowest frequency it's radio waves such as FM and AM radio. Then microwaves, such as ovens and aircrafts that use them. Infrared is next, an example of this would be tv remotes. Light comes after, and this is the only thing the naked eye can view, such as a rainbow. Ultraviolet is next, and this is seen in UV rays. X-rays are second to last in  the spectrum, it's used to see if there's a broken bone and much more. Gamma Rays are last and used in PHET scans.

An example of these two different things would be a thunderstorm. In a thunderstorm you see the lighting strikes first. Then follows the thunder, which reaches you later on because it takes sound longer.

The direction of a light ray is to indicate the angle which the light ray makes with a normal line drawn to the surface of the mirror. The angle of incidence is the angle between this normal line and the incident ray; the angle of reflection is the angle between this normal line and the reflected ray. The law of reflection says the angle of incidence equals the angle of reflection.

Unpolarized light vibrates in multiple planes, but once it passes through a polarizer, the light vibrated in just one plane.

The three colors of light are red, green, and bue, while the primary colors of pigment are red, blue, and yellow. When the primary colors of light overlap they create yellow, magenta, and cyan. When all 3 of the primary colors overlap they make white, unlike when you mix primary colors of paint to make a blackish type color.
