How is photoelectric effect related to intensity?

When a photoelectric effect is observed, the number of electrons ejected is proportional to the intensity of the incident light. The maximum kinetic energy of the photoelectrons increases with higher frequency light.

How does the intensity of radiation affect the photoelectric current?

If we allow radiations of a fixed frequency to fall on any photosensitive material and the accelerating potential between the two electrodes is kept fixed then the photoelectric current is found to be increasing linearly with the intensity of radiation.

How change in frequency and intensity of the radiation affect the photoelectric effect?

If the frequency of electromagnetic waves is higher than the extraction threshold of the metal and electrons are emitted from the metal surface, then an increase of light intensity will result in a proportional increase of electrical current of the electrical circuit where the emitted electrons are conveyed.

How does intensity of a radiation affect the kinetic energy of photons during photoelectric effect?

If the intensity of the incident radiation is increased, there is no effect on the kinetic energies of the photoelectrons. The kinetic energy depends only on the frequency on the light, and hence the energy provided by each photon. This suggests that the photoelectric effect involves one electron and only one photon.

What is photoelectric effect Why is photoelectric current proportional to the intensity of incident radiation?

It’s because intensity is directlyproportional to number of photon in light ray and in photoelectric effect one photon can only release one electron and so more intense light means more photon hence more elections will ejected from the metal surface and hence increasing the photo current .

Why is current proportional to intensity?

Basically, the number of photoelectrons emitted is proportional to the number of photons. We assume/know that each photon is associated with removing an electron from the metal. As the number of photons increase(i.e the intensity increases) the number of electrons increases hence the current increases since I=ne.

Does photoelectric current depends on light intensity?

A. Depends both on intensity and frequency of the incident light.

How does the intensity of photon affect the emission of photoelectric current?

An increase in the intensity of the same monochromatic light (so long as the intensity is not too high), which is proportional to the number of photons impinging on the surface in a given time, increases the rate at which electrons are ejected—the photoelectric current I—but the kinetic energy of the photoelectrons and …

Does photoelectric current depend on intensity?

Yes, the photoelectric current depends on the intensity of incident radiation.

How does the intensity affect the current?

If the frequency of the electromagnetic waves is greater than the metal extraction threshold and electrons are emitted from the metal surface, then an increase in light intensity will result in a proportional increase in the electric current of the electrical circuit where the emitted electrons are conveyed.

Which of the following is dependent on the intensity of incident radiation in a photoelectric experiment?

The photoelectric current depends upon the intensity of incident radiation.

Is current related to intensity?

Current is inversely proportional to the square of the wavelength, while linearly dependent upon light intensity level.

What is the relationship between light intensity and photoelectric effect?

The photoelectric current is directly proportional to the light intensity. The kinetic energy of the photoelectrons is directly proportional to the light frequency. The stopping potential is directly proportional to the frequency and the process is instantaneous. Factors affecting Photoelectric Effect

How does the frequency of the incident photon affect the photoelectron?

If the frequency of the photon is exactly equal to the threshold frequency (𝜈 = 𝜈 th), there will be an emission of photoelectrons, but their kinetic energy will be equal to zero. An illustration detailing the effect of the frequency of the incident light on the kinetic energy of the photoelectron is provided below.

What is the relationship between threshold frequency and photoelectric current?

The threshold frequency varies with material, it is different for different materials. The photoelectric current is directly proportional to the light intensity. The kinetic energy of the photoelectrons is directly proportional to the light frequency.

What is the effect of high intensity on photo current?

High intensity means more number of photons, so chances of hitting to electron by them increase and hence more photo electron are emitted i.e., photo current increases. What happens when you increase the intensity of light?
