In an experiment to measure the photon statistics of thermal light, the radiation from a blackbody source is filtered with an interference filter of bandwidth 0.1 nm centered on 500 nm, and allowed to fall on a photon-counting detector. Calculate the number of modes incident on the detector, and hence discuss the type of statistics that would be expected.

If the photon is actually moving from left to right can I, standing at 90 degrees to the motion, see the photon?
