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.
Q. Figure s (a) and (b) show refraction of a ray in air incident at 60°with the normal to a glass Answer According to the given figure for the glass-air interface:
A ray of light is incident normally on an equilateral prism of refractive index 3/2 calculate devition. Ans) since the prism is equilateral therefore angle of prism is 60 0 =
