when a photon srtikes a metal surface,some of its energy is used to eject electrons from the metal atom and reamining energy is given to the ejected electrons in the form of energy.
This may be expressed as,
Energy of striking photon =Binding energy of metal +kinetic energy of ejected electrons
how much energy is used when we strikes a Proton
it is different for all atoms
sorry when we strikes a electron
it is different
to calcute the energy we use , energy of striking photon = planck's constant *frequency. The value of planck's constant is 6.626*10 raise to power -34 joule *sec
has it helpful to u?
