Question

Match the following :

List - 1	List - 2
a) Burning candle	e) line spectrum
b) Sodium vapour	f) continuous spectrum
c) Bunsen flame	g) bond spectrum
g) Dark lines in solar spectrum	h) Absorption spectrum

• A. a-g, b-e, c-f, d- h
• B. a- g, b-f, c-e, d-h
• C. a-f, b-g, c-e, d-h
• D. a-f, b-e, c-g, d-h

Answer 1

Answer: (D)

a-f, b-e, c-g, d-h

A candle emit light which is when dispersed shows continuous spectrum.

Sodium vapour emits light of wavelengths 589 nm and 589.6 nm when electrical discharge is passed through it, so it shows line spectrum.

Bunsen flame shows bond spectrum.

Dark lines in solar spectrum are absorption spectrum as observed by Fraunhofer.
