In order to increase the stopping potential, there should be increase in
Correct answer: C. Frequency of radiation
- A. Intensity of radiation
- B. Wavelength
- C. Frequency of radiation
- D. Both wavelength and intensity
Explanation
The energy of incident light is directly proportional to its frequency. Hence, the stopping potential increases when the frequency of the incident light is increased.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
