Write the postulates of Einstein’s special theory of relativity.
Question
Write the postulates of Einstein’s special theory of relativity.
Solution
Einstein's Special Theory of Relativity is based on two postulates:
-
The Principle of Relativity: The laws of physics are the same in all inertial frames of reference. This means that there is no "absolute" state of rest in the universe, and all motion is relative.
-
The Constancy of the Speed of Light: The speed of light in a vacuum is the same for all observers, regardless of their motion or the motion of the source of light. This speed is approximately 299,792 kilometers per second.
These two postulates lead to some very counter-intuitive results, such as time dilation and length contraction, which have been experimentally confirmed.
