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.
The light we see the electromagnetic radiation that is boouncing off from an object
Can someone explain the concept of electromagnetic radiation?   The light we see the electromagnetic radiation that is boouncing off from an object,(not sure , it’s not being absorbed or not)?   Someone lelectromagentic radiation is emitted by substances when electrons goes to a lower energy state that is energy is reallease?   Can someone explain more? When a light is transmitted it does nothing to the system?
