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

  1. AIf both assertion and reason are true and the reason is the correctexplanation of the assertion.
  2. BIf both assertion and reason are true but reason is not the correctexplanation of the assertion.
  3. CIf assertion is truebutreason is false.
  4. DIf the assertion and reason both are false.

Correct answer

D. If the assertion and reason both are false.

Step-by-step solution

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