Lorentz Transformation: The postulate of STR is proposed by Einstein in 1905. The two postulates are:
1. Principle of equivalence: According to this "The laws of physics are the same in all inertial frame of references moving with a uniform velocity with respect to one another". Law that hold for one frame of reference cannot be violated for any other inertial observer.
2. Principle of constancy of speed of light: The speed of light in free space is absolute. The value of speed of light is a universal constant and does not depend on the motion of observer and object, it is also independent of direction of motion.
a) Spin motion of electrons b) On the basis of spin and orbital motion of electrons c) These are feebly attracted in an external magnetic field i.e., have a tendency to go fr
Q Define: Drift velocity. Drift velocity is described as the velocity with which free electrons get drifted towards the positive terminal, when an electric field is applied.
Gauss' law: The electric flux by a closed surface is proportional to the algebraic total of electric charges contained in that closed surface; in differential form, div E =
