Question

The ratio of slopes of \( K_{\text{max}} \) vs \( V \) and \( V_0 \) vs \( v \) curves in the photoelectric effect gives

• A. the ratio of Planck’s constant of electronic charge
• B. work function
• C. Planck’s constant
• D. charge of electron

Hint:

In the photoelectric effect, the slope of the graph gives Planck's constant, which relates the energy of a photon to its frequency.

Answer 1

The Correct Option is C

The slope of the \( K_{\text{max}} \) vs \( V \) and \( V_0 \) vs \( v \) graphs gives the value of Planck's constant, as these are related to the energy and frequency of the incident light in the photoelectric effect.
