Question

JEE-ADV CHEM-VOL-
When a certain metal was irradiated with a
light of 8.1 x 1016 Hz frequency, the
photoelectron emitted had 1.5 times the kinetic
energy as the photoelectrons emitted when the
same metal was irradiated with light 5.8 * 1010
Hz frequency. If the same metal is irradiated
with light of 3.846 nm wave length, what will
be the energy of the photoelectron emitted?
A) 1.8 x 102 eV B) 3.65 x 10-17 J
C) 2.28 x 102 eV D) 4.37 10-17 J
