Assertion (A): Between any two given energy levels, the number of absorption transitions is always less than or equal to the number of emission transitions.
Reason (R): Absorption transitions start from the lowest energy level only and may end at any higher energy level. But emission trasitions may start from any higher energy level and end at an energy level below it.
Reason (R): Absorption transitions start from the lowest energy level only and may end at any higher energy level. But emission trasitions may start from any higher energy level and end at an energy level below it.
View answer and explanation
Correct option: A
Both (A) and (R) are true and (R) is the correct explanation of (A)
Option A (Both (A) and (R) are true and (R) is the correct explanation of (A)) is correct because the number of absorption transitions is limited by the availability of electrons in the lowest energy level, while emission transitions can occur from multiple higher energy levels.
