Maximum kinetic energy of a photo electrons can be expressed as ________.
(here, ν, λ = frequency and wavelength of incident energy of photons, νo, λ0 = threshold frequency and wavelength)
1
\(K{E_{max}}\; = {\rm{ }}\left( {h\lambda {\rm{ }} - \;h{\lambda _o}} \right)\)
2
\(K{{E}_{max}}\ =\left( \ h{{\lambda }_{o}} \right)\)
3
\(K{E_{max}}\; = {\rm{ }}\left( {h\nu {\rm{ }} + \;h{\nu _o}} \right)\)
4
\(K{E_{max}}\; = {\rm{ }}\left( {h\nu {\rm{ }} - \;h{\nu _o}} \right)\)
