Question

Short notes on different types of spectrum.​

Answer 1

When we look at objects giving off light (or reflecting light) we find three types of spectra. They are produced in different ways, and can actually tell us about the physical properties of the materials producing the spectra. In many ways it was the development of studying and understanding the spectra of astronomical objects that led to the development of astrophysics as opposed to the more traditional astronomy. This happened from the mid 1800s.

The three types of spectra are called “a continuous spectrum” (or continuum emission), “an emission line spectrum” and “an absorption line spectrum”
