ray optics

The line that passes through the center of a curved mirror is called

• focal point
• center of curvature 
• principle axis
• light ray

The point in the middle way between a curved mirror and the center of curvature is the

• principle point
• focal point
• center of curvature
• principle axis

The distance between the focal point and the mirror is

• raduis
• diameter
• focal point
• focal length

According to the Law of reflection, a light ray striking a mirror

• continues moving through the mirror in the same direction
• moves into the mirror at a slightly different angle
• bounces off the mirror toward the direction it came from
• bounces off the mirror at the same angle it hits.
