Concept of photoelectrics are used in Solar cells,Laser printers. It also show us that Electrons liberate out from the Metal surface due to the energy of photons striking not due to their frequencies.

The photoelectric effect occurs when light of high enough energy strikes an object. When light strikes the object it emits electrons. Now whether electrons are emitted or not depends entirely on the energy of the light and not the intensity of the light. What this simply means is that it does not matter...

The photoelectric effect occurs when light of high enough energy strikes an object. When light strikes the object it emits electrons. Now whether electrons are emitted or not depends entirely on the energy of the light and not the intensity of the light. What this simply means is that it does not matter if the light is bright or dim. What matters is the color (and hence the frequency) of the light. So, if blue light is needed for the emission, a dim blue light can cause the photoelectric effect. But if a red light is used, it may not cause any emission whether a dim or bright source is used. This is extremely important as it clearly shows the the fact that electrons are liberated from an object due to the energy (or frequency) of photons and not the intensity (or amount) of photons striking the material. What this basically meant was that energy levels were 'quantized'. Hence electrons only absorbed a 'fixed' amount of energy and escape as a free particle, or a photo-electron. This led to the concept of wave-particle duality. read less
