Photoelectric current depends on

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.

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. They observed that when a surface is exposed to electromagnetic radiation at a higher threshold frequency, the radiation is absorbed, and the electrons are emitted.

Photoelectric current depends on

In photoelectric effect, the photo current:. The photoelectric current depends on intensity but is independent of the frequency. So, this option is incorrect. Byju's Answer. In photoelectric effect, the photo current: increases with increase of the frequency of incident photon does not depend on the frequency of photon but depends only on intensity of incident light decreases with increase of frequency of incident photon depends both on intensity and frequency of incident beam.

When the light of sufficiently small wavelength is incident on the metal surface, electrons are ejected from the metal instantly. In each case, all other factors remain the same. Answer Detailed Solution Below Option 2 : 1, 2 and 3. Addition of copper to aluminium results in:. Thus, photoelectric current depends upon the intensity of light. When the intensity of incident radiation is increased, the photoelectric current. The DC resistivity of ferrites is many orders of magnitude:. If the frequency is high enough to eject electrons, that's it, the effect starts. What is photoelectric effect? The alloying elements in stainless steel are:. Light of particular frequency v is incident on a metal surface.

The energy quantization of electromagnetic radiation in general, and of light in particular, is expressed in the famous relation. The notion of light quantization was first introduced by Planck. Its validity is based on solid experimental evidence, most notably the photoelectric effect.

For photoelectric current, we first need the photoelectric effect. The DC resistivity of ferrites is many orders of magnitude:. Suggested Test Series. In each case, all other factors remain the same. This results in an increase in the photoelectric current. Open in App. Light of particular frequency v is incident on a metal surface. Option D The photoelectric current depends on intensity but is independent of the frequency. Hot working:. Last updated on Feb 9, Light of intensity 'I' and frequency 'v' is incident on a photosensitive surface and causes photoelectric emission. Verified by Toppr.
