what kind of spectrum do we observe from the sun?
electromagnetic radiation
electromagnetic spectrum refers to the full range of all frequencies of electromagnetic radiation and also to the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. devices used to measure an electromagnetic spectrum are called spectrograph or spectrometer. the visible spectrum is the part of the electromagnetic spectrum that can be seen by the human eye. the wavelength of visible light ranges from 390 to 700 nm. the absorption spectrum of a chemical element or chemical compound is the spectrum of frequencies or wavelengths of incident radiation that are absorbed by the compound due to electron transitions from a lower to a higher energy state. the emission spectrum refers to the spectrum of radiation emitted by the compound due to electron transitions from a higher to a lower energy state.

second solar spectrum









































the second solar spectrum is an electromagnetic spectrum of the sun that shows the degree of linear polarization. the term was coined by v. v. ivanov in 1991. the polarization is at a maximum close to the limb (edge) of the sun, thus the best place to observe such a spectrum is from just inside the limb. it is also possible to get polarized light from outside the limb, but since this is much dimmer compared to the disk of the sun, it is very easily polluted by scattered light.
