The Ratio of `m^(th)` to `n^(th)` wavelength of Lyman series in H-spectrum is equal to

Options

A. `(lambda_(m))/(lambda_(n)) = ((m^(2)-1)xxn^(2))/((n^(2)-1)xxm^(2))`
B. `(lambda_(m))/(lambda_(n)) = ((n^(2)-1)xxm^(2))/((m^(2)-1)xxn^(2))`
C. `(lambda_(m))/(lambda_(n)) =((m+1)^(2))/((n+1)^(2)) xx ((n+1)^(2)-1)/((m+1)^(2)-1)`
D. `(lambda_(m))/(lambda_(n)) =((n+1)^(2))/((m+1)^(2)) xx ((m+1)^(2)-1)/((n+1)^(2)-1)`

Answer

B

Explanation

`bar(v) =(1)/(2)=R[(1)/(n_(1)^(2))-(1)/(n_(2)^(2))]`
