Let `nu_(1)` be the frequency of the series limit of the lyman series `nu_(2)` be the frequency of the first line of th lyman series and `nu_(3)` be the frequency of the series limit of the Balmer series. Then

Options

A. `theta_1- theta_2 = theta_3`
B. `theta_2 - theta_1 = theta_3`
C. `2 theta_3 =theta_1 +theta_2`
D. `theta_1 + theta_2 =theta_3`.

Answer

A

Explanation

`(1)/(lambda) = R ((1)/(1^2)-(1)/(alpha^2))` series for lyman first line
