# Which Transition Corresponds to Emission of Radiation of Maximum Wavelength? - Physics

Which transition corresponds to emission of radiation of maximum wavelength?

#### Solution

E = (hC)/lambda

lambda = (hC)/E

For maximum wavelength, energy transition should be minimum.

A undergoes minimum energy transition.

A = 2 eV

Thus, photon in A will have the maximum wavelength.
