Explanation of Solution
Introduction:
The photoelectric effect is the effect in which the electrons are emitted from a surface on which light of adequate frequency falls.
When the light of minimum frequency falls on the surface then the electrons of the surface gains some energy. If this energy is enough for the emission of the electron from the surface then the flow of photoelectric current starts in the surface. The energy of the photon depends on the frequency of the incident light.
Conclusion:
The photoelectric effect is the effect in which the emission of the electron from the surface occurs due to the energy of the photon.

- A square metal sheet 2.5 cm on a side and of negligible thickness is attached to a balance and inserted into a container of fluid. The contact angle is found to be zero, as shown in Figure a, and the balance to which the metal sheet is attached reads 0.42 N. A thin veneer of oil is then spread over the sheet, and the contact angle becomes 180°, as shown in Figure b. The balance now reads 0.41 N. What is the surface tension of the fluid?
