MCQ
The cause of Fraunhoffer lines is
- AReflection of radiations by chromosphere
- ✓Absorption of radiations by chromosphere
- CEmission of radiations by chromosphere
- DTransmission of radiations by chromosphere
✓
Answer
Correct option: B.
Absorption of radiations by chromosphere
b
(b)When the light emitted from the sun’s photosphere passes through it’s outer part Chromosphere, certain wave lengths are absorbed. In the spectrum of sunlight, a large number of dark lines are seen called Fraunhoffer lines.
