Hydrogen atom absorbs radiations of wavelength `lambda_0` and consequently emit radiations of 6 different wavelengths, of which two wavelengths are longer than `lambda_0`. Chosses the correct alternative(s).

A

The final excited staate of the atoms is n=4

B

The initial state of the atoms is n =2

C

The initial state of the atoms is n =3

D

There ae three transitions belonging to Lyman series

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
`(n_f(n_f-1)/(2) =6`
`rArr n_f =4
`lambda_1` and `lambda_4` are longer than `lambda_0`
`lambda_3,lambda_5 and lambda_6` belong to Lyman series.
