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 medium into another 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.
When light passes at an angle to the normal from one medium into another in which its speed is lower
