Using Balmer empirical formula, obtain the wavelengths of Hα, Hβ, Hγ, Hδ......... H∞

Answer»

Balmer empirical formula is given by 1/λ = R(1/22 - 1/n2)  

For Hα line, put n = 3, 1/λα = R (5/36) where R = 1.097 x 107 m-1 this gives λα = 656.3 nm. 

For Hβ line, put n = 4, 1/λβ = R(3/16), this gives line = 486.1 nm 

For Hγ line, put n = 5, then λγ = 434.1 nm 

For Hδ line put n = 6, then λγ = 434.1 nm 

For H line is called series limit, put n = ∞; λ = 364.6 nm
