The wavelength of the various lines in the hydrogen atomic emission spectrum can be related by a mathematical equation:
`(1)/(lambda) = R ((1)/(n^(2))-(1)/(m^(2)))`
What is the value of `n` for the Pfund series of lines?

A

`6`

B

`5`

C

`4`

D

`3`

Text Solution

Verified by Experts

The correct Answer is:
B
Most of the lines of the Pfund series appear in the far infrared regions.
