When light of suitable frequency is incident on a photosensitive material, photo electrons are ejected and photoelectric current flows. If the intensity of the incident light is increased, then
- A The maximum kinetic energy of photoelectrons will increase
- B The stopping potential will increase
- C The stopping potential will decrease
- D The saturation current will increase
Answer & Solution
Correct Answer
(D) The saturation current will increase
Step-by-step Solution
Detailed explanation
The saturation current will increase In the photoelectric effect, the intensity of incident light is a measure of the number of photons striking the material's surface per unit time. Each incident photon, provided its frequency is above the threshold frequency, can eject one…

A homogeneous mixture of two or more than two components has uniform composition and properties. The binary solutions have two components, which may be solid, liquid or gas. The resultant solution has a larger amount of solvent and a smaller amount of solute. The amount of solute in a given amount of solvent decides the concentration of the resulting solution. The concentration can be expressed in various ways, like molarity, molality, normality and mole fraction.
