21. When a noisy object is moving closer to you, pitch is higher / lower than if it was moving away
from you. (circle one)
22. Scientist are observing a spiral galaxy 6 million light years away. Draw the light waves of the
spiral galaxy to show a red shift in the color spectrum.
23. If we examine the light waves from a star, and we say it is red shifted. What direction is the
star moving? Closer to us or away from us?
24. If we examine the light waves from a star, and we say it is blue shifted. What direction is the
star moving? Closer to us or away from us?
25. The red shifting of galaxies supports which modern theory about the formation of the Universe?
