Question 11 of 155

The de Broglie wavelength of electron of He+ ion is 3.329Å. If the photon emitted upon de-excitation of this He+ ion is made to hit H atom in its ground state so as to liberate electron from it, what will be the de Broglie's wavelength of photoelectron ?

(A) 0.1518 Å

(B) 6.1518 Å

(C) 2.3518 Å

(D) 4.1218 Å
