Vedclass · Answer

(A) In an absorption transition,an electron in a lower energy state absorbs a photon and jumps to a higher energy state. For a system with energy levels $A, B, C$ (where $A In an emission transition,an electron in a higher energy state drops to a lower energy state by emitting a photon. For the same levels,emission can occur from $C \rightarrow B$,$C \rightarrow A$,and $B \rightarrow A$. Thus,there are $3$ possible emission transitions.Since $2 < 3$,the number of absorption transitions is less than the number of emission transitions. The Reason correctly explains that absorption is restricted to starting from the lower level,whereas emission can occur between any two levels where the initial state is higher than the final state.
