Photoelectric current vs intensity graph
WebThe number of emitted photoelectrons increases with the intensity of the incident light. However, the kinetic energy of these electrons is independent of the light intensity. … WebThe graph between the photoelectric current and the intensity of light is a straight line when the frequency of light used is above a specific minimum threshold value. ... The saturation current depends on the intensity for a known value of frequency. At the same time, we see that the stopping potential does not depend on the intensity over a ...
