Photoelectric effect graph slope
Webthe photoelectric effect, the number of electrons emitted is found to increase proportionately with the intensity. It was first thought that increasing the intensity of the ... the slope of the straight line that results will be equal to Planck’s constant divided by the charge of the electron. The WebWhen light shines on a metal, electrons can be ejected from the surface of the metal in a phenomenon known as the photoelectric effect. This process is also often referred to as photoemission, and the electrons that are ejected from the metal are called …
