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

Text Solution

Verified by Experts

The correct Answer is:
A

Dilute `KMnO_(4)` consists of ions. Spectrum of molecule is a band. As the continuous spectrum passes through dilute `KMnO_(4)`, band absorption lines are seen.
