JEE MainPhysicsModerateDual Nature of Matter
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
[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 [IMAGE]
effect will take place)
[IMAGE] No. of photons falling per second [IMAGE] No. of photoelectron emitted per second [IMAGE]
