When the frequency of the incident radiation is doubled kinetic energy of the photoelectrons will be?

When the frequency of the incident radiation on a metallic plate is doubled, KE of the photoelectrons will be. increases but less than doubled.

When the frequency of incident radiations increases in photoelectric effect the kinetic energy of emitted electrons will?

The kinetic energy of photoelectrons at the surface grows linearly with the increasing frequency of incident radiation. Measurements for all metal surfaces give linear plots with one slope.

What is maximum kinetic energy in photoelectric effect?

The maximum kinetic energy KEe of ejected electrons (photoelectrons) is given by KEe = hf − BE, where hf is the photon energy and BE is the binding energy (or work function) of the electron to the particular material.

What happens to the maximum kinetic energy of ejected electrons if the frequency of incident light on a metal is doubled?

As the intensity of the incident light is increased, the energy incident on the metal plate is increased, and the energy absorbed by the individual electrons would increase. The maximum kinetic energy of the emitted electron increases as the frequency of the incident light increases. 2.

When the frequency of light is doubled the energy is?

If the frequency of light in a photoelectric experiment is doubled then maximum kinetic energy of photo electron.

How will the photoelectric current change if the frequency of incident radiation is increased while keeping the intensity of incident radiation constant?

If the intensity of radiation is increased, keeping the frequency fixed, the number of photons per second will increase leading to more collisions per second and transfer of photon energy to more electrons. Thus the number of electrons coming out per second will increase leading to increase in photocurrent.

How does the maximum kinetic energy?

How does the maximum kinetic energy of electrons emitted vary with the work function of the metal? Clearly, smaller the work function W, greater is the Ek. This means that when work function of a metal increases, maximum kinetic energy of photoelectrons decreases.

What will happen to photocurrent IF frequency of incident?

If both the intensity and the frequency of incident light is doubled then the photocurrent remains roughly the same, while the maximum kinetic energy of photo-electrons increases by more than two times. Since we are doubling the frequency, the energy of the photo-electron increases.

What will happen to photocurrent IF frequency of incident light?

A. Depends both on intensity and frequency of the incident light. Increases with increase in frequency of incident light. …

Does photoelectric current depend on kinetic energy?

Yes,surely photoelectric current depends on the intensity and frequency of the radiation as no. of photoelectrons that will emit depend on intensity of light and kinetic energy of them depends on the frequency of light.

What happens if the frequency of incident radiation is doubled?

If the frequency is doubled stopping potial is to be doubled in order to prevent electron emitting from surface. An increase in the frequency of incident radiation increases the maximum kinetic energy of the photoelectrons. How? Remember photon energy is E = h f, h is Planck constant, and f is the frequency.

What happens to the photocurrent when the frequency of light is doubled?

If both the intensity and the frequency of incident light is doubled then the photocurrent remains roughly the same, while the maximum kinetic energy of photo-electrons increases by more than two times. Since we are doubling the frequency, the energy of the photo-electron increases.

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.

How does the kinetic energy of a photoelectron change with frequency?

The maximum kinetic energy of the photoelectrons is found to increase with the increase in the frequency of incident light, provided the frequency (γ > γ Th) exceeds the threshold limit. The maximum kinetic energy is independent of the intensity of light.
