Question

A photo-cell is being operated in saturation mode. Electromagnetic radiations of wavelength λ m fall upon the photo-cell. The corresponding spectral sensitivity of photocell is J A W - 1 . The number of photo-electrons produced by each incident photon, is, h c 2 e λ J, h c J e λ, 2 h c J e λ, 2 h c e λ J

MARKS App · Accepted Answer

Power of source P = n ⋅ h c λ ...(i) n → no. of incident photons per second Photo current I = n ' e ...(ii) n ' → no. of electrons reaching anode per second ⇒ n ' n = I e × h c P λ = h c e ⋅ λ I P = h c J e λ
