Refraction, Reflection, Diffraction

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

According to the Law of reflection, a light ray striking a mirror

• moves into the mirror at a slightly different angle

• bounces off the mirror toward the direction it came from

• bounces off the mirror at the same angle it hits.
