Monochromatic radiation of wavelength la...

Monochromatic radiation of wavelength `lambda` is incident on a hydrogen sample in ground state. Hydrogen atoms absorb a fraction of light and subsequently emit radiations of six different wavelength . Find the wavelength `lambda`.

A

`9.75 nm`

B

`50nm`

C

`85.8nm`

D

`97.25nm`

Text Solution

Verified by Experts

The correct Answer is:
D
For six different spectral lines, requilred transitions is `4 rarr 1`
`(1)/(lambda) = R_(H)z^(2) [(1)/(n_(1)^(2))-(1)/(n_(2)^(2))]`
