A

line emission spectrum

emission of band spectrum

C

line absorption spectrum

D

none of the above

Text Solution

Verified by Experts

The correct Answer is:
C

Fraunhofer lines are a set of spectral lines. These lines were originally observed as dark features in the optical spectrum of the sun. It was discovered by kirchhoff that each chemical element was associated with a set of spectral lines and deduced that the dark lines in the solar spectrum were caused by absorption by those elements in the upper layers of the sun. Hence, Fraunhofer line of the solar system is an example of line absorption specturm.
