Chapter 37: Q. 1 (page 1081)

What are the wavelengths of spectral lines in the Balmer series with $n = 6, 8, a n d 10$ ?

Short Answer

Expert verified

The wavelengths with $n = 6, 8, 10$ are $410.31 n m, 389.03 n m a n d 379.92 n m$ respectively.

Step by step solution

Given information

We need to find the wavelengths of spectral lines in the Balmer series with $n = 6, 8, 10$ .

Explanation

Now the Rydberg formula for Balmer series is

$\frac{1}{2^{2}} - \frac{1}{n^{2}} = \frac{91.18 (n m)}{位} 位 = \frac{91.18 (n m)}{\frac{1}{2^{2}} - \frac{1}{n^{2}}}$

This is equation (1)

Now on substituting n value we get-

$F o r$ $n = 6$

$位_{6} = \frac{91.18 (n m)}{\frac{1}{2^{2}} - \frac{1}{6^{2}}} 位_{6} = 410.31 n m F o r n = 8, 位_{8} = \frac{91.18 (n m)}{\frac{1}{2^{2}} - \frac{1}{8^{2}}} 位_{8} = 389.03 n m F o r n = 10, 位_{10} = \frac{91.18 (n m)}{\frac{1}{2^{2}} - \frac{1}{10^{2}}} 位_{10} = 379.92 n m$
