Problem

A bright line of wavelength 656.3 nm656.3\,\text{nm} is recorded in the emission spectrum of hydrogen. (Take RH=1.097×107 m−1R_H = 1.097\times10^{7}\,\text{m}^{-1}.) (i) Identify the spectral series to which this line belongs. (ii) Calculate the principal quantum number of the higher energy level involved in the transition.
