Problem: For this question consider the figure to the right shows an energy level diagram for a certain atom (not hydrogen). Several transitions are shown and are labeled by letters.a.) Which transition corresponds to the absorption of a 413 nm photon? b.) Which transition corresponds to the emission of a 248 nm photon?

FREE Expert Solution

Emission occurs only when electrons get transformed from the outer orbit to the inner one (higher energy level to lower energy level).

Absorption is when electron gets from inner orbit to outer orbit.

The transition from 4 to 2 and 2 to 1 is emission.

On the other hand, the transition from 1 to 3 or 2 to 3 or 3 to 4 is absorption

a)

Energy corresponding to this transition is, E = hc/(413 × 10-9) = (6.63 × 10-34)(3.0 × 108)/(413 × 10-9)(1.6 × 10-19)  = 3 eV
