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.
WORK AND ENERGY 1. Work can be defined as: the force applied in direction of displacement ×. This means that if the force F acts at an angle θ with respect to the direct
concept of position and displacement
The fringe width in a Young's double slit arrangement is 0.008cm. What could be the fringe width if the slit separation is halved and the screen slit distance is doubled?
What is inertia?
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?
a. A certain radioactive material emits gamma rays with energy 1 MeV. Another sample of radioactive material emits gamma rays with energy 10 keV. If both of these emit the same amo
when dispersion is happening from a prism, the colors are separated out. do each of these colors move with different velocities to keep frequency constant? practically is it possib
It uses in electric cooling devices, turbines ...........etc
Methods of Demagnetization: 1. A magnet loss it's magnetic properly when it is heated strongly. 2. Practically a magnet can be demagnetized by hammering when it is placed in
Lorentz was the first to obtain the equations which relate the space and time coordinate of two frames of reference moving with a constant velocity with reference to each other and
