Which waves do light travel in?

It is scattered.
What happens when light hits a smooth surface?
It is reflected evenly.
What are the two angles in the Law of reflection diagram?

What is the change of speed and direction when light hits a transparent surface?
Refraction
Why can you see an image in a mirror?
You can see an image in a mirror because the reflected rays of light appear to come from a point behind the mirror.
Vacuum
A completely empty space containing no particles
Longitudinal wave
A wave where particles vibrate in the same direction as the wave is travelling.
