← A beam of 5.0 × 10¹⁵ photons each second falls on a photocell. Of every hundred photons, 4.5 free an electron. What is the photocurrent? Use e = 1.6 × 10⁻¹⁹ C.For light of wavelength λ the stopping potential of a cathode is 0.65 V. For light of wavelength λ/2 it is 2.85 V. Find the work function of the cathode. →
