Smuggler's Run: Doppler Effect

As water gets more dense, what does it do?

• It rises

• It sinks

• It moves faster

• It becomes blue

What does the Doppler effect explain about the light of approaching and receding stars?

• The light becomes invisible.

• The light changes color.

• The light remains constant.

• The light stops moving.

• red

• green

• yellow

What can astronomers learn from observing red shifts in galaxies?

• The galaxies are getting colder.

• The galaxies are moving towards us.

• The galaxies are moving away from us.

• The galaxies are changing color.
