Photocurrent vs intensity graph
WebFeb 11, 2024 · I was puzzled by the behavior of the simulation until I read the PhET Tips for Teachers of the Photoelectric Effect (same page as the software on Phet site):. In the default setting, since the intensity of light is proportional to the number of photons times the frequency, if you increase the frequency while holding the intensity constant, the number … WebPhotocurrent linearity is determined by measuring the small change in photocurrent as a result of a small change in the incident light power as a function of total photocurrent or incident light power. Non-Linearity is the variation of the ratio of the change in photocurrent to the same change in light power, i.e. ∆I/∆P.
