The ratio of minimum to maximum wavelength in Balmer series is

Options

A. `5 : 9`
B. `5 : 36`
C. `1 : 4`
D. `3 : 4`

Answer

A

Explanation

`(1)/(lambda) = R[(1)/(n_(1)^(2)) - (1)/(n_(2)^(2))] rArr (lambda_(min))/(lambda_(max)) = [[(1)/(2^(2)) - (1)/(3^(2))])/[[(1)/(2^(2)) - (1)/(oo)]) = (5)/(9)`
