The emission spectrum of hydrogen discovered first and the region of the electromagnetic spectrum to which it belongs respectively are -

A

Lyman Ultravoilet

B

Lyman Visible

C

Balmer, Ultravoilet

D

Balmer, Visible

Text Solution

Verified by Experts

The correct Answer is:
D
In 1885, Balmer for the first time showed that the wave numbers of spectral lines present in the visible region in hydrogen spectrum are given by:
`barv(cm^(-1))=109677((1)/((2)^(2))-(1)/(n_(2)^(2)))`
Hence, `n_(2)=3, 4, 5` ……..
Hence, the Balmer spectrum of hydrogen was discovered first and it lies in visible region.
