Scientist use telescopes to make distant objects appear closer. Some parts of a telescope are shown above. Which of the following best describes how the objective lens of this telescope helps a scientist observe a moon?

• The objective lens produces light

• The objective lens blocks light

• The objective lens reflects light

The picture above shows a child standing in a swimming pool. Why does the lower part of a 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.
