refraction effects
The @[email protected] flux emitted from the interior of a rectangular sample reaching a photodetector place at some distance from the sample is decreased by a factor of approximately \(n^{2}\) (where \(n\) is the @[email protected] of the medium) compared with a medium whose @[email protected] is 1.0. Such effects are termed refraction effects.
