Q. The transition from the state $n = 4$ to $n = 3$ in a hydrogen like atom result in ultraviolet radiation. Infrared radiation will be obtained in the transition from
A) $2 \rightarrow 1$
B) $3 \rightarrow 2$
C) $4 \rightarrow 2$
D) $5 \rightarrow 4$
Explanation
(d) $\lambda_{IR} > \lambda_{UV}$ also wavelength of emitted radiation $\lambda \propto \frac{1}{\mathrm{\Delta}E}$
