Refraction is the bending of a wave disturbance as it passes from one _________ into another.

• glass
• medium
• area
• boundary

Atmospheric refraction of light rays is responsible for which of the following effects? 

• spherical abberation
• mirages
• chromatic abberation
• total internal reflection in a gemstone

Which of the following describes what will happen to a light ray incident on a glass-to-air boundary at greater than the critical angle?

• total internal reflection
• total external transmission
• partial reflection, partial transmission
• partial reflection, total transmission

How is light affected by an increase in the index of refraction?

• Its frequency increases
• Its frequency decreases
• Its speed increases
• Its speed decreases

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

• it is bent towards the normal.
• it always lies along the normal.
• it is unaffected.
• it is bent away from the normal.

When light passes at an angle to the normal from one material into another material 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.
