Photoelectric current depends on

Use app Login. In photoelectric effect, the photocurrent depends both on intensity and frequency of the incident light.

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.

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.

Suggested Exams. Option D The photoelectric current depends on intensity but is independent of the frequency.

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.

Light of particular frequency v is incident on a metal surface. When the intensity of the incident photon increases, the number of electrons emitted from the metal surface increases. In photoelectric effect, the photocurrent depends both on intensity and frequency of the incident light. Photoelectronic current depends on the intensity of the light and is independent of the frequency of incident light. The property related to hard magnetic materials is:. Light of intensity 'I' and frequency 'v' is incident on a photosensitive surface and causes photoelectric emission. 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. Reason: Increases in intensity of given light increases the kinetic energy of photo-electron. Suggested Exams. If the frequency is high enough to eject electrons, that's it, the effect starts. Explain, giving justification in each case. The current that flows through a material due to the photoelectric effect is known as the photoelectric current. This is a great opportunity for Engineering Graduates. The correct option is B does not depend on the frequency of photon but depends only on intensity of incident light Explanation for correct option: Option B When electromagnetic radiation hits a material, some electrons are emitted from it.
