When the wave of hydrogen atom comes from infinity into the first then the value of wave number is

A

`109700 cm^(-1)`

B

`1097 cm^(-1)`

C

`109 cm^(-1)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
Wavenumber `bar(v) = (1)/(lambda) = R [(1)/(n_(1)^(2)) - (1)/(n_(2)^(2))] , n_(2) = oo` and `n_(1) = 1`
`rArr bar(v) = R = 1.097 xx 10^(7) m^(-1) = 109700 cm^(-1)`
