JEE PYQ: Atomic Structure Question 38
Question 38 - 2019 (09 Jan Shift 1)
For emission line of atomic hydrogen from $n_i = 8$ to $n_f = n$, the plot of wave number against $\frac{1}{n^2}$ will be:
(1). (Linear with intercept $-R_H$)
(2). (Non linear)
(3). (Linear with slope $R_H$)
(4). (Linear with slope $-R_H$)
Show Answer
Answer: (4)
Solution
$\bar{\nu} = \frac{R_H}{64} - \frac{R_H}{n^2}$. Plot of $\bar{\nu}$ vs $\frac{1}{n^2}$ is linear with slope $-R_H$.
