Fraunh offer line of the solar system is an example of:

1. line absorption specturm
2. emission of line system
3. line emission spectrum
4. emission of band spectrum

Correct answer: line absorption specturm

Solution

Fraunhofer lines are dark lines in the Sun’s continuous spectrum caused by cooler gases absorbing specific wavelengths. That makes them a line absorption spectrum, not an emission spectrum.
