Consider the situation as given in the figure. | |||
| |||
Assume that the light consists of a stream of photons, all with the same energy hn and with momentums given by k. | |||
Assume a certain flux of photons (= number per second and cm2) given by Iin, Iref, and Itr. Also assume that you have "mirror" reflection, i.e. both angles are identical (= a) | |||
Show that you obtain Itr = Iin – Iref and Snellius law (sina/sinb = n) from energy and momentum conservation. | |||
