A beam of electromagnetic radiation of intensity
[IMAGE] is comprised of wavelength,
[IMAGE] It falls normally on a metal (work function
[IMAGE] ) of surface area of [IMAGE]. If
one in [IMAGE] photons ejects an electron, total number
of electrons ejected in[IMAGE] is
[IMAGE] then x is....
Show answer and solution
Energy of photon. [IMAGE] (so photoelectric
effect will take place)
[IMAGE] No. of photons falling per second
[IMAGE] No. of photoelectron emitted per second
effect will take place)
[IMAGE] No. of photons falling per second
[IMAGE] No. of photoelectron emitted per second
