(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.
This is the virtue of a material resists flow of electric current. It should be as high as possible. When material is subjected to an electrical pressure then will always be a flow

Q. What is dual character of light? Light behaves as particles of energy in the higher energy region as well as as waves in the lower energy region.
A beam of light of wavelength λ = 5000Å falling normally on a plane diffraction grating. The 1 st order spectrum is derived in a direction making an angle θ 1 with the norma
A transformer takes a current of 0.8A when its primary is connected to a 240 volt, 50Hz supply, the secondary being on open circuit. If the power absorbed is 72 watts, Determi
COLLISION: "When two or more bodies come close to each other, so that there is some part of interaction among them, with or without the presence of external force, we say tha
