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 is 3 x 100000000(meter/sec. Basically the answer of this question lies in the Einstein postulates … Continue reading

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 and from Addition of velocity relation u = (u’ + v)/ (1 + u’(v/c2)) Suppose … Continue reading
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 transformations equations are derived by Lorentz for these objects and these are known as Lorentz … Continue reading

MichelsonMorley experiment
Aim of the MichelsonMorley experiment: The MichelsonMorley experiment was done to confirm the presence of hypothetical medium called ether. Therefore, one question should be there what was ether? Yes, I have used “was ether” not “is ether”. Let us discuss … Continue reading

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 mesons are the particles formed in the earth atmosphere. The half life time of µ … Continue reading
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 with the velocity of the light. Let us derive and discuss the variation of mass … Continue reading
Relativistic addition of velocity
Let there are two inertial frames of references S and S’. S is the stationary frame of reference and S’ is the moving frame of reference. At time t=t’=0 that is in the start, they are at the same position … Continue reading
Relativistic energymomentum relation derivation
Relativistic energy momentum relation: From Einstein mass energy relation E = mc2 (1) Also from variation of mass with velocity relation m = m0/(1 – v2/c2)1/2 (2) Where m0 is the rest mass of the object Put value of m … Continue reading
