Continuous spectrum is produced by

A

incandescent electric lamp

B

mercury vapour lamp

C

sodium vapour lamp

D

the sun

Text Solution

Verified by Experts

The correct Answer is:
A
Incandescent electric lamp gives continuous emission spectrum. Mercury and sodium vapour lamp give line emission spectrum.
The Fraunhofer lines seen in the sun's spectrum whereas the cooler vapurs in the sun's atmosphere emit line spectra corresponding to the elements present.
