• stopped
• reflected
• refracted

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

• continues moving through the mirror in the same direction
• 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.
