Question:

While conducting a photoelectric effect experiment with the light of a certain frequency, you find that a reverse potential difference of 1.25 V is required to reduce the current to zero.

Find

a) the maximum kinetic energy and

b) the maximum speed of the emitted photoelectrons.

Photoelectric effect:

When the light of certain frequency generally greater than the threshold frequency incident on a metal plate, electrons start emitting from the metal surface which will be having some kinetic energy and since photons are used to eject electrons the phenomenon is known as photoelectric emission.
