Question

In the photoelectric effect, the velocity of ejected electrons depends upon the nature of the target and (A) The frequency of the incident light (B) The polarisation of the incident light (C) The time for which the light has been incident (D) The intensity of the incident light

Tardigrade Admin · Accepted Answer

In photoelectric effect,
Maximum kinetic energy

=

incident energy

-

work function
Since work function is constant ,so maximum kinetic energy will depend on incident energy and hence The velocity of photoelectrons depends upon the frequency of the incident light

Q. In the photoelectric effect, the velocity of ejected electrons depends upon the nature of the target and

The frequency of the incident light

The polarisation of the incident light

The time for which the light has been incident

The intensity of the incident light

In photoelectric effect, Maximum kinetic energy = incident energy − work function Since work function is constant ,so maximum kinetic energy will depend on incident energy and hence The velocity of photoelectrons depends upon the frequency of the incident light

In photoelectric effect,
Maximum kinetic energy $=$ incident energy $-$ work function
Since work function is constant ,so maximum kinetic energy will depend on incident energy and hence The velocity of photoelectrons depends upon the frequency of the incident light
