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.

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

• makes the water in the glass evaporate
• reflects the pencil on the water's surface

Why would a box painted white look brighter than boxes painted in darker colors?

• back into the fiber

• around the fiber

• in a curve

Which of these best demonstrates the reflection of light?

• Looking through the glass of a large window

• Looking at an image formed on a silver spoon
