Question

With regard to photoelectric effect, identify the correct statement among the following

• A. Number of e⁻ ejected increases with the increase in the intensity of incident light
• B. Energy of e⁻ ejected increases with the increase in the intensity of incident light
• C. Number of e⁻ ejected increases with the increase in the frequency of incident light
• D. Number of e⁻ ejected increases with the increase in work function

Answer 1

The Correct Option is A

In the photoelectric effect, the number of electrons ejected from a material increases with the intensity of the incident light, as intensity is directly related to the number of photons striking the material. However, the energy of the ejected electrons is dependent on the frequency of the incident light, not the intensity. The work function (the minimum energy required to eject an electron) is a characteristic of the material and does not affect the number of electrons ejected.

The correct option is (A): Number of e⁻ ejected increases with the increase in the intensity of incident ligh
