AQA A Level Physics 3.3.2.3 Refraction at a plane surface

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 enters and leaves the water

• bends when it is inside water

• reflects the pencil on the water's surface

The refractive index will always be:

As light enters these materials it...

• continues its straight line path

• bends toward the normal

• bends away from the normal

• reflects
