chaitanyaj: but how i have written explain it

Answered by parul5880

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

chaitanyaj: how much energy is used when we strikes a Proton

parul5880: it is different for all atoms

chaitanyaj: sorry when we strikes a electron

parul5880: it is different

parul5880: 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

parul5880: has it helpful to u?
