A) Solar spectrum
B) The spectrum obtained from the neon lamp
C) Spectrum from a discharge tube
D) None of the above
The black lines in the solar spectrum are called Fraunhofer lines. The elements in the outer atmosphere (chromosphere) of the Sun absorb the light of their characteristics wavelengths coming from Sun’s inner atmosphere (photosphere). This is the cause of the existence of Fraunhofer lines. Therefore, option A is correct.
