Photoelectric EffectHard

Question

Two separate monochromatic light beams A and B of the same intensity (energy per unit area per unit time) are falling normally on a unit area of a metallic surface. Their wavelength are λA and λB respectively. Assuming that all the incident light is used in ejecting the photoelectrons, the ratio of the number of photoelectrons from beam A to that from B is

Options

A.
B.
C.
D.

Solution

The number of photo electron depends on the number of photons
Number of photon = ∝ λ
Ratio of no. of photo electrons
        =
