In which of the following transition will the wavelength be minimum ?

A

`n_(4) rarr n_(1)`

B

`n_(2) rarr n_(1)`

C

`n_(4) rarr n_(2)`

D

`n_(3) rarr n_(1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`Delta E = h nu =h(c )/(lambda)`
or `lambda = (hc)/(Delta E)` i.e., `lambda prop (1)/(Delta E)`
`Delta E = E_(4) - E_(1)` will be maximum and hence `lambda` will be minimum.
