Classical Mechanics Level 4

The radius of the orbit of an electron in a Hydrogen-like atom is $$4.5a_0$$, where $$a_0$$ is the bohr's radius.It's orbital angular momentum is $$\frac{3h}{2\pi}$$.It is given that 'h' is Planck's constant and R is Rydberg constant.The possible wavelengths when the atom de-excites is/are:-
1) $$\frac{9}{32R}$$ 2)$$\frac{9}{16R}$$ 3)$$\frac{9}{5R}$$ 4)$$\frac{4}{3R}$$
