Does the stopping potential depend on the frequency of the incident light?
In presence of stopping potential, the largest kinetic energy is the initial kinetic energy, which it has at the surface of electrodes. Thus the stopping potential depends upon the frequency of the incident light and the material of the metal surface.
How does stopping potential vary with frequency of incident light?
The stopping potential is varying with frequency of incident light. An increase in frequency of the incident light will increase the kinetic energy of the emitted electrons, therefore greater retarding potential is needed to stop them.
Is stopping potential proportional to frequency?
Ans: Stopping potential is directly proportional to the frequency of incident radiation. The stopping potential is more negative for higher frequencies of incident radiation.
What are the factors on which stopping potential depends?
stopping potential depends on the frequency of the incident light. Answer: It depends upon the frequency of the incident Light.
Why does stopping potential increase frequency?
An increase in frequency of the incident light increases the kinetic energy of the emitted electrons, so greater retarding potential is required to stop them completely. This means that work done by stopping potential must just be equal to maximum kinetic energy of an electron.
How does stopping potential depend on wavelength?
When a centimeter thick surface is illuminated with ligh of wavelength λ, the stopping potential is V. When the same surface is illuminated by light of wavelengh2λ, the stopping potential is V/3.
Why does stopping potential depends on frequency?
For a given intensity of radiation, the stopping potential depends on the frequency. Higher the frequency of incident light higher the value of stopping potential.
Why stopping potential does not depend on the intensity of light having same frequency?
The stopping potential does not change with the radiation intensity because the kinetic energy of photoelectrons (see (Figure)) does not depend on the radiation intensity.
When the frequency of the incident light is less than the threshold frequency?
When the frequency of incident radiation becomes equal to threshold frequency, the blue of stopping potential becomes zero. When the frequency of incident radiation becomes less than threshold frequency no photoelectric emission take place. Hence, the involvement of stopping potential does not arise.
How does frequency and intensity of incident photons effect stopping potential?
(a) Photoelectric current in a photocell increases with the increase in the intensity of the incident radiation. (b) The stopping potential (V0) varies linearly with the frequency (ν) of the incident radiation for a given photosensitive surface with the slope remaining the same for different surfaces.
What happens to stopping potential when frequency is increased?
Does the stopping potential in the photoelectric emission depend upon a the intensity of the incident radiation B the frequency of the incident radiation?
No, the stopping potential does not depend upon the intensity of incident radiation but depends on the nature of photosenstive surface and frequency of the incident radation.
Is stopping potential dependent on the intensity of the incident light?
It is not dependent on the intensity of incident light. On rising intensity, the value of current increases, but the stopping potential keeps constant. When the frequency of incident light is higher the value of stopping potential also becomes high. The unit of stopping potential is volt.
What happens when the frequency of incident light is higher?
When the frequency of incident light is higher the value of stopping potential also becomes high. The unit of stopping potential is volt. In the photoelectric experiment, light is focused on a metal plate and if the frequency of light is sufficient enough, electrons are ejected from the surface.
What does the stopping point of an emitter depend on?
The stopping potenial depends on frequency of incident light and nature of the emitter material.for a given frequency of incident light, it is independent of its intensity. Was this answer helpful?
What is the unit of stopping potential in photoelectric experiment?
The unit of stopping potential is volt. In the photoelectric experiment, light is focused on a metal plate and if the frequency of light is sufficient enough, electrons are ejected from the surface. These electrons then progress to a second metal plate placed at a distance parallel to it.
