Why would a wave change direction?

• Because it kept traveling through the same medium
• Because it went from one medium to another
• the amplitude was too large
• the frequency was too small

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
