The wavelength of the first line of Balmer series is 6563 Å. The Rydberg constant for hydrogen is about |
1.09 × 107 per m 1.09 × 108 per m 1.09 × 109 per m 1.09 × 105 per m |
1.09 × 107 per m |
$\frac{1}{\lambda}=R\left[\frac{1}{4}-\frac{1}{9}\right]=\frac{5 R}{36}$ ∴ R = $\frac{36}{5 \lambda}=\frac{36}{5 \times 6563 \times 10^{-10}}=1.09 \times 10^7 m^{-1}$ |
