What is the postulates of special theory of relativity?
Answers
postulates of special theory of relativity.
1. First postulate :
The laws of physics are the same in all inertial frames of reference.
2. Second postulate:
As measured in any inertial frame of reference, light is always propagated in empty space with a definite velocity c that is independent of the state of motion of the emitting body.
Explanation:
THE FUNDAMENTAL POSTULATE OF THEORY OF RELATIVITY IS
▶THE LAWS OF SCIENCE SHOULD BE SAME FOR ALL FREELY MOVING OBSERVERS, NO MATTER WHAT IS THIER SPEED.
THIS WAS TRUE FOR NEWTON'S LAWS LAWS OF MITION, BUT NOW THE IDEA WAS EXTENDED TO INCLUDE MAXWELL'S THEORY AND THE SPEED OF LIGHT.
ALL OBSERVERS SHOULD MEASURE THE SAME SPEED OF LIGHT, NO MATTER HOW FAST THEY ARE MOVING. THIS SIMPLE IDEA HAS SOME REMARKABLE CONSEQUENCES. PERHAPS THE BEST KNOWN WAS THE EQUVALANCE OF MASS AND ENERGY SUMMED UP IN EINSTEIN'S FAMOUS EQUATION E=MC^2 .
