Chemistry - Atomic Structure Question with Solution | TestHub

Two photons strike on two different metal surfaces A & B . If following information is given

(i) $\frac{{\mathrm{KE}}_{\text{max }}(\mathrm{A})}{{\mathrm{KE}}_{\text{max }}(\mathrm{B})}=\frac{1}{3}$

(ii) If maximum kinetic energy of photoelectron from surface B is equal to kinetic energy of electron in $2^{\text{nd }}$ orbit of H -atom.

(iii)

Then calculate work function of the metal (∅_A) for metal "A" in eV
