Continuous emission spectrum is produced by

Options

  1. Ain candescent electric lamp
  2. Bmercury vapour lamp
  3. Csodium vapour lamp
  4. Dpolyatomic substances

Correct answer

A. in candescent electric lamp

Step-by-step solution

In candescent electric lamp produces continuous emission spectrum whereas mercury and sodium vapour given line emission spectrum. Polyatomic substance such as H ₂, CO ₂ and KMNO ₄ produces band absorption spectrum.
