Eddington limit (Sir A. Eddington)
The theoretical limit on which the photon pressure would go above the gravitational attraction of light-emitting body. i.e., a body emitting radiation at greater than the Eddington restrictions would break up through its own photon pressure.
Q Define threshold frequency? The minimum frequency of incident radiation lower which the photoelectric emission isn't possible completely but high the intensity of incident r
Why rotation of rigid bodies through finite angles not a vector? Ans) Because it does not obey one of the laws of vector algebra(law of commutativity).
