Photoelectric current depends on

In photoelectric effect, the photo current:. The photoelectric current depends on intensity but is independent of the frequency.

Use app Login. In photoelectric effect, the photocurrent depends both on intensity and frequency of the incident light. Open in App. Verified by Toppr. The correct option is B does not depend on the frequency of incident light but depends on the intensity of the incident light.

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.

Verified by Toppr. In photoelectric effect, the photo current. In photoelectric effect, the photocurrent depends both on intensity and frequency of the incident light.

How these experiments led to the idea of light behaving as a particle of energy called a photon.

Photoelectric current depends on

When a metal surface is exposed to a monochromatic electromagnetic wave of sufficiently short wavelength or equivalently, above a threshold frequency , the incident radiation is absorbed and the exposed surface emits electrons. This phenomenon is known as the photoelectric effect. Electrons that are emitted in this process are called photoelectrons. The target material serves as the anode, which becomes the emitter of photoelectrons when it is illuminated by monochromatic radiation. We call this electrode the photoelectrode.

Last updated on Feb 9, Light of particular frequency v is incident on a metal surface. The DC resistivity of ferrites is many orders of magnitude:. View Solution. Coulomb blockade can be readily observed when the single electron charging energy is larger than. In photoelectric effect, the photoelectric current is independent of. What will be the effect on anode current when i the intensity of light is gradually increased, ii the frequency of incident radiation is increased, and iii the anode potential is increased? Trusted by 5. The typical range of dissipation factor D of capacitor is. Verified by Toppr. If the frequency is high enough to eject electrons, that's it, the effect starts.

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.

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. The content of carbon in plain and low carbon steels is up to:. Addition of copper to aluminium results in:. The DC resistivity of ferrites is many orders of magnitude:. More will be the number of photons, more will be the electrons no. Light of intensity 'I' and frequency 'v' is incident on a photosensitive surface and causes photoelectric emission. This results in an increase in the photoelectric current. This phenomenon is called the photoelectric effect. This phenomenon is known as the photoelectric effect. The property related to hard magnetic materials is:.
