Which of the following statements are true concerning special relativity?
a. Clocks moving relative to an observer are measured by that observer to run more slowly compared to clocks at rest.
b. The laws of physics have the same form in all inertial reference frames.
c. Light propagates through empty space with a definite speed independent of the speed of the source or observer.
d. Time can no longer be regarded as an absolute quantity.
e. The length of an object is measured to be shorter when it is moving relative to the observer than when it is at rest.
The theory of special relativity is founded on two new postulates.
The first postulate states that the laws of physics remain the same in all inertial reference frames.
The second postulate states that the speed of light in vacuum is measured to be the same in all inertial reference frames.
These postulates lead to several new phenomenon not found in classical physics such as moving clocks ticking slower than stationary clocks (time dilation) objects being shorter when moving (length contraction), and observers moving relative to one another measuring different amounts of time for the same event.
