In the Bending Light Lab, how does the angle of incoming light compare to the angle of light reflecting off of the surface of the water?

• The angle of the incoming light is the SAME as the angle of light reflecting off the surface of the water.

• The angle of the incoming light is GREATER than the angle of light reflecting off the surface of the water.

• The angle of the incoming light is LESS than the angle of light reflecting off the surface of the water.

A student placed a pencil in a cup of water.  The pencil appears broken because light-

• always travels in a straight line
• bends when it passes through water
• makes the water in the glass evaporate
• reflects the pencil on the water's surface

The pictures shows what a student observed when he looked through a hand lens at a penny.
What happens to light passing through a hand lens that makes the image of the penny appear larger? The light is-

• absorbed
• reflected
• refracted
• stopped

Why does the lower part of the child appear so much different in size from the upper part?

• The light rays that travel through water and then into air are refracted.
• The light rays that travel through water and then into air are enlarged.
• The light rays that travel through air and then into water are reflected.
• The light rays that travel through air and then into water are reduced.
