A spaceship is approaching a space station at a speed of 2.55 multiply.gif 105 m/s. The space station has a beacon that emits green light with a frequency of 5.95 multiply.gif 1014 Hz.
(a) What is the frequency of the beacon observed on the spaceship? (Carry five digits in these calculations. Use c = 2.9979 multiply.gif 108 m/s for the speed of light. State your answer to five significant figures.) WebAssign will check your answer for the correct number of significant figures.
Hz
(b) What is the change in frequency?
