If frequency of incident radiation in photoelectric effect is increased beyond threshold frequency, it will effect:

Explanation

If the frequency of the incident radiation in the photoelectric effect is increased beyond the threshold frequency, it will affect the stopping potential. The stopping potential refers to the minimum potential difference required to stop the flow of photoelectrons in a photoelectric experiment. When the frequency of the incident radiation is increased beyond the threshold frequency, the kinetic energy of the emitted photoelectrons increases. As a result, a higher stopping potential is needed to counteract this increased kinetic energy and stop the photoelectrons.
