Problem

The radius of the orbit of an electron in a Hydrogen-like atom is

4.5 a_0

, where

a_0

is the Bohr radius. Its orbital angular momentum is

\frac{3\hbar}{2\pi}

. It is given that

\hbar

is Planck constant and

R

is Rydberg constant. The possible wavelength(s), when the atom de-excites, is (are) [Adv. 2013] a.

\frac{9}{32R}

\frac{9}{16R}

\frac{9}{5R}

\frac{4}{3R}
