PhysicsDual Nature of Matter and RadiationMHT CET 2026

In photoelectric effect experiment, if the frequency of incident radiation (v) is increased, keeping all other factors constant, the stopping potential, (v > v) (v = threshold frequency)

Answer: (C)

Solution

Einstein's photoelectric equation gives , so . Thus the stopping potential varies linearly with the frequency; when is increased (with ) the
