11.1 Einstein’s Postulates
1
Which of the following statements describes the Michelson-Morley experiment?
- The speed of light is independent of the motion of the source relative to the observer.
- The speed of light is different in different frames of reference.
- The speed of light changes with changes in the observer.
- The speed of light is dependent on the motion of the source.
11.4 Relativistic Addition of Velocities
2
What happens when velocities comparable to the speed of light are involved in an observation?
- Newton’s second law of motion, , governs the motion of the object.
- Newton’s second law of motion, , no longer governs the dynamics of the object.
- Such velocities cannot be determined mathematically.
- None of the above
