Optics Review

All rays that are parallel to the principle axis in a concave mirror reflects 

• Towards the focal point

• Away from the focal point

• Towards the center of curvature

• Away from the center of curvature

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.

When light passes at an angle to the normal from one medium into another in which its speed is higher

• it is bent toward the normal.

• it always lies along the normal.

• it is unaffected.

• it is bent away from the normal.

What happens to light during total internal reflection?

• The angle of incidence is greater than the critical angle.

• The angle of reflection is the same as the critical angle.

• The angle of refraction is less than the critical angle.

• The angle of incidence is zero.
