Question:

a. The Doppler effect is the varying frequency of the sound made by a train whistle as the train approaches and then moves away from you. The Doppler effect is also used to measure the speed of stars in space relative to the earth. Explain this effect on the basis of what you know about the relationship of wavelength, speed of light or sound, and frequency.

b. On a cold day, the speed of sound decreases. What effect would that have on the sound of the train whistle?
