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

When light passes at an angle to the normal from one material into another material in which its speed is higher 

• it is bent toward the normal.
• it always lies along the normal.
• it is unaffected.
• it is bent away from the normal.
