Answer

It has been proved that the normalization for the case $l = 2, m_{l} = 卤 2$ is correct.

Step by step solution

Given data

$Thewavefunctioncorrespondingto (l, m_{l}) = (2, 卤 2) is, 螛_{l, m_{l}} (胃) 桅_{m_{l}} (蠒) = \sqrt{\frac{15}{32 蟺}} \sin^{2} 胃 e^{卤 2 i 蠒}$

Normalization

$TheangularpartoftheHydrogenatomwavefunctionshouldsatisfytheconditionas: {鈭�}_{0}^{蟺} {螛_{l, m_{l}} (胃)}^{2} 2 蟺 s i n 胃 d 胃 = 1$

Determining whether the given normalization constant is correct

In the given wave function,

$螛_{l, m_{l}} (胃) = \sqrt{\frac{15}{32 蟺}} \sin^{2} 胃$

Check equation (I) as,

$= \frac{15}{32 蟺} 脳 2 蟺 {鈭�}_{0}^{蟺} \sin^{5} 胃 d 胃 = \frac{15}{16} {鈭�}_{0}^{蟺} \sin^{4} 胃 \sin 胃 d 胃 = \frac{15}{16} {鈭�}_{0}^{蟺} {(\sin^{2} 胃)}^{2} \sin 胃 d 胃 = \frac{15}{16} {鈭�}_{0}^{蟺} {(1 - \cos^{2} 胃)}^{2} \sin 胃 d 胃$

Let us assume,

$\cos 胃 = z - \sin 胃 d 胃 = d z$

Then the integral becomes,

$= \frac{15}{16} {鈭�}_{1}^{- 1} {(1 - z^{2})}^{2} (- d z) = \frac{15}{16} {鈭�}_{- 1}^{1} (1 + z^{4} - 2 z^{2}) d z = \frac{15}{16} {[z + \frac{z^{5}}{5} - 2 \frac{z^{3}}{3}]}_{- 1}^{1} = \frac{15}{16} (2 + \frac{2}{5} - \frac{4}{3}) = 1$

Thus the normalization is correct.
