Question

White light is passed through a dilute solution of potassium permagnate. 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)

Band absorption spectrum

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 $Band$ $Absorption$ $Spectrum$.
