5.4 Refraction of Waves F4

When the frequency of a wave increases, what happens to the wavelength?

• The wavelength is not directly affected by the frequency of a wave.
• The wavelength increases.
• The wavelength decreases.
• More specific information is needed to form a conclusion about the wavelength.

Which wave in the diagram has the greatest frequency?

• 1
• 2
• 3
• 4

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

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.

• Reflection
• Refraction
