Answer:
Yes, electrons with energy of 1.3ev will be emitted from the metal surface
Explanation:
From Eisenstein's photoelectric equation;
KE= E - Wo
Where;
KE= kinetic energy of the emitted photoelectron = ??
E= Energy of the photon =4.5 ev
Wo= work function of the metal = 3.2ev
KE= 4.5 ev - 3.2 ev
KE= 1.3 ev
