Photoelectric effect - frequency depedence

Press the START button to start the animation.

This animation shows the effect of the fequency of the incident radiation on the emission of an electron from the surface. All the potential wells are of equal depth and so the have equal work functions.

The higher energy violet quanta cause photoelectrons to be ejected from the surface.
