Assertion: It is essential that all the lines available in the emission spectrum will also be available in the absorption spectrum.
Reason: The spectrum of hydrogen atom is only absorption spectrum.

Options

A. If both assertion and reason are ture and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reson are false.

Answer

D

Explanation

Erassion transitions can take place between any higher energy level and any energy level below it while absorption transitions start from the lowest enregy level only and may end at any higher energy level,Hence number of absorptions transitions between two given energy level. Hence number of absorption trasitions between two given energy levels is always the same two levels.
