An electron in hydrogen atom after absorbing-an energy photon jumps from energy state `n_(1)` to `n_(2)`. Then it returns to ground state after emitting six different wavelengths in emission spectrum.'The energy of emitted photons is either equal to, less than or grater than the absorbed photons: Then `n_(1)` and `n_(2)` are:

A

`n_(2) = 4, n_(1) = 3`

B

`n_(2) = 5, n_(1) = 3`

C

`n_(2) = 4, n_(1) = 2`

D

`n_(2) = 4, n_(1) = 1`

Text Solution

Verified by Experts

The correct Answer is:
C
On coming from `4 rarr 1` energy is greater than, less than or equal to energy corresponding to `2 rarr 4`
