MCQ
The black lines in the solar spectrum during solar eclipse can be explained by
- APlanck's law
- ✓Kirchoff's law
- CBoltzmann's law
- DSolar disturbances
✓
Answer
Correct option: B.
Kirchoff's law
b
Kirchhoff's Law states that the ratio of the emissive power to absorptive power for the radiation of a given wavelength is same for all substances at the same temperature. This explains the astronomical behaviour in a solar spectrum where a number of dark lines called Fraunhoffer lines are observed.But during solar ecllpse, same bright lines are observed as that of Fraunhoffer dark lines.
