Noether theorem (Noether):
A theorem which revels that symmetries are what gives increase to conserved quantities. For example, translational symmetry (the fact that the laws of physics work the similar in all places) gives increase to conservation of momentum, as position & momentum are complementary. In addition, conservation of energy is mention by time symmetry, & conservation of angular momentum is mentioned by isotropy.
The substances which acquire charges on rubbing are said to be charged. The electricity produced by friction is called Frictional force. If the charges do not move, then the frict
It is an instrument used to view pure spectrum. It makes dispersion without deviation with the help of n crown prisms and (n - 1½ flint prisms alternately arranged in a tabular str

Radius of gyration may be explained as the distance from the axis at which, if the entire mass of the object were to be concentrated, the moment of inertia would be the same about

In an isothermal process, the temperature of body always same throughout the process. As the internal energy of a system depends only on its temperature, thus there is no modificat
Explain why a narrow slit is used in case of Bi-prism experiment where as an extended source is used in Newton's rings experiment?
The electrostatic shielding may be found by protecting and enclosing the sensitive instruments inside a hollow conductor due to inside hollow conductors, electric fields is zero.
Cosmological redshift An effect where light emitted through a distant source seems redshifted due to the expansion of spacetime itself.
Define Eddy Currents ? If you try to pull a solid piece of some metals (good electrical conductors) quickly between the poles of a strong magnet, you will feel a force pushing
