Question

The transition from the state n = 4 to n = 3 in a hydrogen like atom results in ultraviolet radiation. Infrared radiation will be obtained in the transition from (A) 2 → 1 (B) 3 → 2 (C) 4 → 2 (D) 5 → 4

IR corresponds to least value of ((1/n21)-(1/n22)) i.e. from Paschen, Bracket and Pfund series. Thus the transition corresponds to 5 â 3.

Q. The transition from the state $n = 4$ to $n = 3$ in a hydrogen like atom results in ultraviolet radiation. Infrared radiation will be obtained in the transition from

$2 \to 1$

$3 \to 2$

$4 \to 2$

$5 \to 4$

IR corresponds to least value of $(\frac{1}{n _{1}^{2}} - \frac{1}{n _{2}^{2}})$
i.e. from Paschen, Bracket and Pfund series. Thus the transition corresponds to $5 \to 3.$
