MHT CET Physics question

PhysicsDual Nature of Matter and RadiationMHT CET

Light of wavelength which is less than threshold wavelength is incident on a photosensitive material. If incident wavelength is decreased, so that emitted photoelectrons are moving with same velocity, then stopping potential will [MHTCET 2016]

Answer: (A)

Solution

Decreasing the wavelength raises the photon energy, so the maximum kinetic energy of the photoelectrons rises and
