Balmer series

Vedclass · Answer

(B) The Balmer series of the hydrogen spectrum lies in the visible region of the electromagnetic spectrum.The wavelengths of the lines in this series are given by the Rydberg formula: $\frac{1}{\lambda} = R \left( \frac{1}{2^2} - \frac{1}{n^2} \right)$,where $n = 3, 4, 5, \dots$.The longest wavelength (for $n=3$) is $6563 \, \mathring{A}$,and the shortest wavelength (for $n=\infty$) is $3646 \, \mathring{A}$.Both of these values fall within the visible light range.
