Refraction

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

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

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.
