• Light is refracted as it moves from one medium to another medium.

• Light travels in a straight line and can be reflected off the surface of the water.

• Light is absorbed by water and reflected off glass.

The diagram below shows a fish being viewed from above the water.

The fish appears to be closer to the surface than it really is. What causes this difference?

• Light is reflected.

• Light is refracted.

• Light is focused.
