• 39.7 degrees
• 19.2 degrees

• accelerate while it is in glass
• increase its speed
• reduce its speed

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.
