Question

Which of the following transitions corresponds to the emission of the radiation of the maximum wavelength?

Options

• I

• III

• IV

• VI

Answer 1

IV

Explanation:

Transitions III, V and VI correspond to absorption of energy.

Maximum emitted wavelength corresponds to minimum energy difference.

ΔE_I > ΔE_II > ΔE_IV

Therefore, the maximum emitted wavelength corresponds to transition IV.
