When it moves through a new material

What is the law of reflection?

Angle in = angle out

What is the focal point?

Point where light rays meet

What can light waves travel through?

Empty space, solids, liquids, or gases

Which mirror gives a wide-angle view?

convex

If the angle between the incident ray and the reflected ray is 90°, what is the angle of incidence?

45°

What is refraction?

Bending of light when it passes from one medium to another

Which type of mirror is used in telescopes?

concave

A ray strikes a mirror, and the reflected ray makes a 50° angle with the surface. What is the angle of incidence?
