Which of the following transitions have minimum wavelength

A

`n_(4)ton_(1)`

B

`n_(2)ton_(1)`

C

`n_(4)ton_(2)`

D

`n_(3)ton_(1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`DeltaE=(hc)/(lamda)` that is, `lamdaprop(1)/(DeltaE)` so `DeltaE=E_(4)-E_(1)` will be maximum and hence `lamda` will be minimum.
