In a photo electric experiment the maximum velocity of photo electons ...
Yes, the maximum velocity of photoelectrons depends on the frequency of the incident radiation. In the photoelectric effect, the energy of the incident photons is transferred to the photoelectrons, which are then emitted from the metal surface. The maximum kinetic energy of the photoelectrons is directly proportional to the frequency of the incident radiation, and this determines the maximum velocity of the photoelectrons. Therefore, option C is correct.

Explanation:
Photoelectric effect is a phenomenon where electrons are emitted from a metal surface when it is exposed to electromagnetic radiation such as light. In this experiment, the maximum velocity of photoelectrons emitted is measured.
Frequency of incident radiation:
The maximum velocity of photoelectrons depends on the frequency of incident radiation. This is known as the Einstein’s photoelectric equation.
Einstein’s photoelectric equation:
E = hf = Φ + ½ mv²
where,
E = energy of photon
h = Planck’s constant
f = frequency of incident radiation
Φ = work function of the metal (minimum energy required to remove an electron from its surface)
m = mass of the electron
v = velocity of the electron
From the above equation, we can see that the velocity of the electron depends on the energy of the photon (hf) and the work function of the metal (Φ). The energy of a photon is directly proportional to the frequency of radiation. Therefore, the velocity of the electron is also directly proportional to the frequency of radiation.
Other options:
a) Intensity of incident radiation:
The intensity of incident radiation does not affect the maximum velocity of photoelectrons. It only affects the number of photoelectrons emitted.
b) Cathode material:
The maximum velocity of photoelectrons depends on the cathode material. Different metals have different work functions, which affect the maximum velocity of photoelectrons.
d) Wavelength of incident radiation:
The wavelength of incident radiation is indirectly proportional to the frequency of radiation. However, the maximum velocity of photoelectrons depends on the frequency of radiation, not the wavelength.
