Problem: What does special relativity reveal about the speed of light relative to its source? a. Light moves at the same speed independent of the motion of the source. b. Light moves more slowly if emitted by a source moving in the direction of emission. c. Light moves faster if emitted by a source moving in the direction of emission. d. Light moves more slowly if emitted by a source moving in the direction opposite the emission. e. Light moves faster if emitted by a source moving in the direction opposite the emission.
