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 $= 9:4$.
