Question

With regard to photoelectric effect, identify the correct statement among the following., Energy of electron ejected increases with the increase in the intensity of incident light., Number of electron ejected increases with the increase in the frequency of incident light., Number of electron ejected increases with the increase in work function., Number of electron ejected increases with the increase in the intensity of incident light.

MARKS App · Accepted Answer

Photoelectric effect takes place when the rays of light falls on the surface of a metal with low ionisation energy, ejection of electrons from the surface of the metal takes place. The frequency of light being used, should be suitable. Also, the number of electrons emitted is directly proportional to the intensity of light but does not depend upon its frequency. However, the velocity of the emitted electrons is dependent on frequency of light used.
