Relativity

Can someone travel faster than speed of light

Can there be something faster than speed of light? This is the question that occasionally come into mind of physics students. The speed of light

Common queries related to theory of relativity-1

Q1. Who proposed the theory of relativity? Ans: Albert Einstein. Q2. What is the difference between general theory of relativity and special theory of relativity?

No signal can travel faster than the speed of the light

Proof that no signal can travel faster than the speed of the light. Solution: Method 1 As relativistic addition of velocity relation is already derived

Lorentz transformation equations for space and time

Results of Galilean Transformation equations can not be applied for the objects moving with a speed comparative to the speed of the light. Therefore new

Michelson-Morley experiment

Aim of the Michelson-Morley experiment: The Michelson-Morley experiment was done to confirm the presence of hypothetical medium called ether. Therefore, one question should be there

Real life example of time dilation

Real example of time dilation: As we have already discussed the concept of time dilation. Let us discuss its example: Decay of µ- mesons: µ-

Variation of mass with velocity and its derivation

Do you know that there is variation of mass with velocity in relativity that is mass varies with the velocity when the velocity is comparable

Relativistic addition of velocity
