Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): An absorption spectrum consists of dark lines in an otherwise continuous bright spectrum. Reason (R): Atoms absorb radiation of certain wavelengths from white light, leaving dark spaces. In the light of the above statements, choose the correct answer from the options given below:

  1. Both (A) and (R) are true and (R) is the correct explanation of (A).
  2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
  3. (A) is true but (R) is false.
  4. (A) is false but (R) is true.

Correct answer · Option 1

Both (A) and (R) are true and (R) is the correct explanation of (A).

Explanation

When white light passes through a sample, missing wavelengths corresponding to absorbed radiation leave dark spaces in the continuous spectrum.
