Why does the lower part of the child appear so much different in size from the upper part?

• The light rays that travel through water and then into air are refracted.
• The light rays that travel through water and then into air are enlarged.
• The light rays that travel through air and then into water are reflected.
• The light rays that travel through air and then into water are reduced.

Which of these statements about light is correct?

• If there is nothing to interfere with light waves, they should travel in a straight line.

• Light waves will always travel in a straight line, even if they come into contact with another object.

• Light waves don't travel in a straight line.

• Light waves travel in a straight line because sound waves travel in a straight line.

What is the angle of incidence?

• The angle at which light bends in water.

• The angle at which light hits a surface.

• The angle at which light is absorbed by an object.

• The angle at which light bounces off a surface.
