(a) State the postulate of STR and deduce Lorentz Transformation.
OR
Give basic postulate of special theory of relativity. Derive Lorentz Transformation equations.
(b) Prove that particle having rest mass zero is always moving with velocity of light.
What is half wave plate? Explain its action on polarized light incident on it with its electric vector E making an angle with the optic axis of the half wave plate.
EXAMPLES: (i) A book lying on the table remains at rest until it is listed or pushed by exerting a force. (ii)A rolling ball on the ground comes to rest after covering some
