Question
A photocell in the saturation mode is irradiated by light of wavelength λ = 6600 (Ao). The corresponding spectral sensitivity of the cell is sλ = 4.8 mA/W. Find the yield of photoelectrons, i.e. the number of photoelectrons produced by each incident photon. [Take : h = 6.6 × 10-34 J-s]
Options
A.9 × 10-2
B.9 × 10-4
C.9 × 10-3
D.9
Solution
Let nelectron be the number of electrons and nphoton be the number of photons
Sλ =
Sλ =
