The follwing diagram indicates the energy levels of a certain atom when the system moves from `2E` level to `E`, a photon of wavelength `lambda` is emitted. The wavelength of photon produced during its transition from `(4E)/(3)` level to `E` is

A

`(lambda)/(3)`

B

`(3lambda)/(4)`

C

`(4lambda)/(3)`

D

`3 lambda`

Text Solution

Verified by Experts

The correct Answer is:
D
`2E - E = E = (hv)/(lambda)`
`(4)/(3)E = (E)/(3) =? :.` New wave length `= 3lambda`
