The energy levels of a hypothetical atom are shows below. Which of the shown transitions will result in the emission of a photon of wavelength 275 nm?

Which of these transitions correspond to emission of radiation of (i) maximum and (ii) minimum wavelength?

Answer:

Wavelength associated :

For A:

Energy change: E1-E2 = 0 - (-2) = 2 eV

So wavelength of the radiation emitted is:

(wavelength emitted is 256 nm, i.e, radiation B)

Maximum wavelength : emission A

Minimum wavelength: emission D
