Question

White light is passed through a dilute solution of potassium permanganate. The spectrum produced by the emergent light is

• A. band emission spectrum
• B. line emission spectrum
• C. band absorption spectrum
• D. line absorption spectrum

Answer 1

Answer: (C)

when light is passed through the solution then some part of the complete electromagnetic spectrum will be absorbed by the solution. So, the emitted spectrum will have some missing $E.M$. waves of frequency corresponding to what has been absorbed by the solution. So, the emergent light produced will be Band Absorption Spectrum.
