Question

In infrared region of hydrogen spectrum ,the numberof types of spectral line series formed are

Answer 1

Answer:

they are 3

I.e. 1st is p fund series. 2nd is bracket series 3rd is paachan series

Answer 2

The number of spectral lines formed in the Infrared region is 6.

Given,

Hydrogen Spectrum series

To Find,

Number of spectral lines formed in the Infrared region

Solution,

The infrared regions are -

Paschen (n = 3) → Electrons from n = 4, 5, 6 can return this state. Thus total number of spectral lines = 3

Brackett (n = 4) → Electrons from n = 5, 6 can return this state. Thus total number of spectral lines = 2

Pfund (n = 5) → Electrons from n = 6 can return this state. Thus total number of spectral lines = 1

Total number of lines = 3 + 2 + 1

Total number of spectral lines = 6
