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) $$\frac{4}{3R}$$
