Absorption Reflection Refraction

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.

How is refraction different from reflection.

• Reflection is the bouncing of light off an object and refraction is the bending of light when it moves through one kind of matter to another.

• Reflections is the bending of light when it moves through one kind of matter to another and refraction is the bouncing of light off an object.
