Hint: the photoelectric effect happens when the light of the frequency is higher than the threshold frequency of the metal. In the photo, the electric effect light is considered to contain the energy packets. The frequency is directly proportional to every energy packet.
Complete step by step solution:
Due to the incident radiation, the photoelectrons emitted from a metal surface are called photoelectric currents.
The photoelectric current doesn’t depend on the frequency. The incident radiation frequency influences the kinetic energy of the emitted photons. The saturation current is independent of the incident ray frequency.
If we apply the positive potential at the collector plate then it gives the electric field and it attracts more photoelectrons. Here the photoelectron's reach gets increased when we increase the positive potential on the collector plate.
The number of packets hitting per unit time is called intensity. The number of electrons emitted per unit area is determined by the magnitude of the photoelectric current. The incident light's frequency gives the incident photon energy.
So, the answer is an option (B).
Note:
The photocurrent depends on the energy of a photon that hits the surface of metal should have an energy greater than the threshold energy. When the photons have so much energy we can get more photocurrent. If the intensity is high then the photocurrent is high the photocurrent depends on the intensity of light. If the light intensity is fixed for an increasing voltage then the current gets saturated.
