Photoelectric Effect Explained in Simple Words for Beginners

Photoelectric effect occurs when electromagnetic radiation above the threshold frequency of the given metallic surface, strikes the surface and releases electrons from it. This happens because light is made of massless particles called photons, which possess a certain amount of energy. When these photons strike the surface, they knock electrons off it; we call these photoelectron.
Just because a light ray has a high intensity doesn't mean that it will cause the photoelectric effect. It can only happen if the frequency of the light rays is equal to or greater than a given value-known as the threshold frequency-of the metal. In this video, we have explained the photoelectric effect, threshold frequency and the work function in simple words
