Continuous emission spectrum is produced by
- A incandescent electric lamp
- B mercury vapour lamp
- C sodium vapour lamp
- D polyatomic substances
Answer & Solution
Correct Answer
(A) incandescent electric lamp
Step-by-step Solution
Detailed explanation
Incandescent electric lamp produces continuous emission spectrum whereas mercury and sodium vapour give line emission spectrum. Polyatomic substances such as \(\mathrm{H}_{2}, \mathrm{CO}_{2}\) and \(\mathrm{KMnO}_{4}\) produces band absorption spectrum.
