QUESTION:

Armed with highly sensitive detection equipment, you are in the front of a railroad car that is accelerating forward. Your friend at the rear of the car shines green light toward you. Do you find the light to be red-shifted (lowered in frequency), blue-shifted (increased in frequency), or neither? Explain. (?Hint: Think in terms of the principle of equivalence. What is your accelerating railroad car equivalent to?)
