A spaceship is approaching a space station at a speed of1.8 x 105 m/s. The space station has a beacon that emits green light by a frequency of 5.96 x 1014 Hz. What is the frequency of the beacon observed on the spaceship? (Express your answer to five important figures.)
What is the change in this frequency?
