WebJan 20, 2012 · 1.For a given metal and frequency of incident radiation, the rate at which photoelectrons are ejected is directly proportional to the intensity of the incident light. 2.For a given metal, there exists a certain minimum frequency of incident radiation below which no photoelectrons can be emitted. This frequency is called the threshold frequency. Webresponse, which is the frequency at which the photodiode output decreases by 3dB. It is roughly approximated by: ( 3 ) There are three factors defining the response time of a photodiode: 1. t ... to light, and it is defined as the ratio of the photocurrent I P to the incident light power P at a given wavelength: ( 5 ) In other words, it is a ...
