Ratio of the wavelengths of first line of Lyman series and first line of Balmer series is 5 : X then find X.

Text Solution

Verified by Experts

The correct Answer is:
27
`1/lambda = R (1/n_1^2 -1/n_2^2)`
For first line of Lymen series `n_1 = 1` and `n_2 = 2`
For first line of Balmer series `n_2 = 2` and `n_2 = 3`
So, `lambda_("Lymen")/(lambda_"Balmer") = 5/27`
