Light of wavelength \( 5000 \mathrm{~A} \) falls on a sensitive plate with photoelectric work function of \( 1.9 \mathrm{eV} \). The
\( \mathrm{P} \) kinetic energy of the photoelectron emitted will be
W
(1) \( 1.24 \mathrm{eV} \)
(2) \( 2.48 \mathrm{eV} \)
(3) \( 0.58 \mathrm{eV} \)
(4) \( 1.16 \mathrm{eV} \)
