When the light of sufficiently small wavelength is incident on the metal surface, electrons are ejected from the metal instantly. This phenomenon is called the photoelectric effect. Last updated on Feb 9, This is a great opportunity for Engineering Graduates. Get Started. English Hindi. This question was previously asked in. Answer Detailed Solution Below Option 2 : 1, 2 and 3. Start Now. The photocurrent generated depends on the following factors: 1 Frequency of the incident light Frequency is an important factor because it decides whether the effect will take place or not. For photoelectric current, we first need the photoelectric effect.

When light strikes materials, it can eject electrons from them. This is called the photoelectric effect , meaning that light photo produces electricity. One common use of the photoelectric effect is in light meters, such as those that adjust the automatic iris on various types of cameras. In a similar way, another use is in solar cells, as you probably have in your calculator or have seen on a roof top or a roadside sign. These make use of the photoelectric effect to convert light into electricity for running different devices. This figure shows an evacuated tube with a metal plate and a collector wire that are connected by a variable voltage source, with the collector more negative than the plate. When light or other EM radiation strikes the plate in the evacuated tube, it may eject electrons. If the electrons have energy in electron volts eV greater than the potential difference between the plate and the wire in volts, some electrons will be collected on the wire.

The photoelectric effect is a phenomenon in which electrons are ejected from the surface of a metal when light is incident on it. These ejected electrons are called photoelectrons. The process through which photoelectrons are ejected from the surface of the metal due to the action of light is commonly referred to as photoemission. The photoelectric effect occurs because the electrons at the surface of the metal tend to absorb energy from the incident light and use it to overcome the attractive forces that bind them to the metallic nuclei. An illustration detailing the emission of photoelectrons as a result of the photoelectric effect is provided below. The photoelectric effect was first introduced by Wilhelm Ludwig Franz Hallwachs in the year , and the experimental verification was done by Heinrich Rudolf Hertz.

If the frequency is high enough to eject electrons, that's it, the effect starts. Light of particular frequency v is incident on a metal surface. When the light of sufficiently small wavelength is incident on the metal surface, electrons are ejected from the metal instantly. The Photon Model.
