The frequency of the spectral line obtained when the electron in `n = 3` of Hydrogen atom drops to the ground state is 

A

`2.925xx10^(15)` Hertz

B

`2.925xx10^(13)` Hertz

C

`2.925xx10^(13)` Hertz

D

`36559xx10^(10)` Hertz

Text Solution

Verified by Experts

The correct Answer is:
A

`upsilon = cbar(upsilon)= cR((1)/(n_2^2) - 1/(n_2^2))`
`=3xx10 xx 109677 [1/1 -1/9]`
`=32.9xx10^(14) [8/9] = 2.925 xx 10^(15) Hz`
