A photon of energy 8eV is incident on a metal plate with threshold frequency 1.6 xx 10^(15) Hz. The maximum kinetic energy of the emitted photo electrons is (given h= 6 xx 10^(-34) Js )

A photon of energy 8 eV is incident on a metal surface of threshold frequency 1.6 xx 10^(15) Hz , then the maximum kinetic energy of photoelectrons emitted is ( h = 6.6 xx 10^(-34) Js)

A photon of energy 10.2eV collides inelastically with a stationary hydrogen atom in the ground state. After a time interval of the order of a microsecond, another photon collides with energy of 15eV. What will be observed by the detector ?
