Answer:

$Work \: function \: of \: plate ϕ=1.9 e \\ Wavelength \: of \: incident \: photon \: λ=5000 \: Ao=500 nm \\ Energy \: of \: the \: incident \: photon \: Eincident \: =λ \: (in nm) \: 1240 eV \\ ⟹ Eincident \: = \: 5001240 \: = \: 2.48 eV \\ Maximum kinetic \: energy \: of \: photon \: emitted \\ K.Emax \: = \: Eincident−ϕ</p><p> \\ ⟹ K.Emax \: =2.48−1.9 = 0.58 eV$

$Maximum \: kinetic \: energy \: of \: photon \: emitted \: is \: 0.58eV.$

$I \: hope \: this \: helps \: you$
