1. The spectrum of the hydrogen atom in the visible range is shown in the figure. Please figure out the formulation of these line as a function of wavelength.
氢原子的谱线我就不放上来了,波长是410.2,434.0,486.1,656.3/nm
其实这是量纲的计算吧?

由H的光谱项公式,有
1/λ=R*(1/m^2-1/n^2),R为Rydberg常数,m,n为正整数,m<n

在可见光的巴尔末系中,m=2,可以改写为
λ=B*n^2/(n^2-4),B=364.56nm为Balmer常数

在上述谱线中
λ=410.2nm:对应m=2,n=6
λ=434.0nm:对应m=2,n=5
λ=486.1nm:对应m=2,n=4
λ=656.3nm:对应m=2,n=3
