Question

Solar spectrum is an example for
A. line emission spectrum
B. continuous emission spectrum
C. band absorption spectrum
D. line absorption spectrum

Answer 1

Hint: When we have seen via a prism, the spectrum is the range of colors of wavelength energies emitted by a light source. So, we can say that the solar spectrum is a continuous line with millions of dark absorption lines overlaid on it. Also, the spectra can be distributed into two types such as emission and absorption spectra.

Complete step by step solution:
We can say that the solar spectrum is a line absorption spectrum since it is made up of a continuum with millions of dark absorption lines overlaid on top. The lines are known as the Frauenhofer lines. And the solar spectrum is also known as the Frauenhofer spectrum. These lines are created mostly in the photosphere. The solar spectrum includes wavelengths varying from gamma rays to radio frequencies. Hence, the solar spectrum is an example of a line absorption spectrum.

Therefore, the correct option is (D).

Additional Information:The solar spectrum's highest radiation strength lies about 500 nm, near the blue end of the visible range. The ultraviolet (UV), visible (Vis), and infrared (IR) wavelengths make up the whole spectrum.

Note:Many students make mistakes in understanding the concept of the spectrum. We can say that the emission spectrum is produced as a result of the radiation emitted by the substances whereas the absorption spectrum is generated as a result of the substances' absorption of radiation.
