The diagram shows the energy levels for an electron in a certain atom. Which transition shown represent the emission of a photon with the most energy ?

A

III

B

IV

C

I

D

II

Text Solution

Verified by Experts

The correct Answer is:
A
The enrgy of emitted photon is directly proportional to the difference of the two energy levels. This differences is maximum between level (2) and level (1) hence photon for maximum energy will be librated for this transition only.
