A beam of light has three wavelengths 4144 4,4972 A and 62164 with a total intensity of 3.6x10 Wn equally distributed amongst the three wavelengths. The beam falls normally on an area 1.Ocm of a clean metallic surface of work function 2.3eV. Assume that there is no loss of light by reflection and that each energetically capable photon ejects one electron. The number of photo electrons liberated in per second

    and here here wavelength's energy is less than the given work function so photo current is not possible

    I will check this again and then tell you... wait
  • Anshum Sharma
    work function is the minimum energy required to eject electrons W = hv⁰.. i.e I have taken this

    Yes I know but energy of photon is not the work function...

    Here is the detailed solution

    how you have taken work function as energy of photon??🙄🙄
