Malus' law (E.L. Malus):
The light intensity I of a ray along initial intensity I0 travelling by a polarizer at an angle theta among the polarization of the light ray & the polarization axis of the polarizer is specified by I = I0 cos2 theta.
When Temperature increases,intensity increases,but in some time intensity decreases,Why?

Determine the Einstein relations by upward and downward transition. While the system is in equilibrium, the upward and downward transition rates should be equal. N 1 ρ(ν) B
Conclusion of photoelectric effect
Magnus effect: In a moving fluid a rotating cylinder drags some of the fluid around with it, in its direction of rotation. This enhances the speed in that region, and therefor
