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

A

I

B

II

C

III

D

IV

Text Solution

Verified by Experts

The correct Answer is:
C
`1^("st")` transition is showning absorption of a photon. From rest of three transitions, III is having maximum energy from level n = 2 to n = 1
`DeltaE=((1)/(n_(1)^(2))-(1)/(n_(2)^(2)))`
