H-alpha light is the brightest hydrogen line in the visible spectral range. See the answer. This formula gives a wavelength of lines in the Balmer series of the hydrogen spectrum. The representation of the hydrogen emission spectrum using a series of lines is one way to go. Balmer’s formula can therefore be written: \frac{1}{\lambda}=R_H(\frac{1}{2^2}-\frac{1}{n_2^2}) Calculating a Balmer Series Wavelength. For the Balmer series, the wavelength is given by \[\frac{1}{\lambda} = R\left[ \frac{1}{2^2} - \frac{1}{n_2^2} \right]\] The longest wavelength is the first line of the series for which Identify the final product of the given reaction.
