Light of wavelength 500 nm is incident on a metal with work function 2.28 eV. The de Broglie wavelength of the emitted electron is
≤ 2.8 × 10–12 m
< 2.8 × 10–10 m
< 2.8 × 10–9 m
≥ 2.8 × 10–9 m

Light of wavelength ‘λ’ 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
