Is Threshold Frequency The Same For All Metals?

by

Is Threshold Frequency The Same For All Metals? The precise shape of the surface of a metal will determine exactly where and how electrons move in the metal. Therefore, the threshold frequency and work function can vary. Does threshold frequency depend on the metal? Threshold frequency is the minimum frequency of incident light which can

How Did Einstein Prove That Light Was A Particle? The explanation is very simple: the packets of energy are very tiny, so tiny that you don’t notice the bumps. … Einstein thought “If energy comes in packets, then light could come in packets too!”, he called this packets photons and now everything made sense. What
