The given diagram indicates the energy levels of a certain atom. When the system moves from 2E level to E level, a photon of wavelength `lamda` is emitted. The wavelength of the photon emitted during its transition from 4E/ 3 level to E level is

A

`lamda//3`

B

`3lamda//4`

C

`4lamda//3`

D

`3lamda`

Text Solution

Verified by Experts

The correct Answer is:
D
`2E - E=(hc)/lamda," " (4E)/(3)-E=(hc)/(lamda.)`
Dividing, `E/(E//3)=(lamda.)/(lamda), lamda.=3lamda`
