JEE PYQ: Atomic Structure Question 31
Question 31 - 2019 (09 Apr Shift 1)
For any given series of spectral lines of atomic hydrogen, the ratio $\frac{\Delta\bar{\nu}{Lyman}}{\Delta\bar{\nu}{Balmer}}$ is:
(1). (4 : 1)
(2). (9 : 4)
(3). (5 : 4)
(4). (27 : 5)
Show Answer
Answer: (2)
Solution
$\Delta\bar{\nu}{Lyman} = R_H/4$, $\Delta\bar{\nu}{Balmer} = R_H/9$. Ratio $= 9:4$.
