This is normally done by passing it through a prism.

White light is a mix of different frequencies; with certain equipment, it is possible to separate it into its components. This separated version is called a "spectrum".White light is a mix of different frequencies; with certain equipment, it is possible to separate it into its components.

thermogram.
Visible light rays
Spectrum means a band of colors that comes about when the various components of light are separated by their different refraction degrees.
Visible Spectrum
Separating light into various colors produces a spectrum or rainbow.
A glass prism is the best way to see how light can be separated into the full spectrum of color. A cut crystal piece will also break the light up.
Visible Spectrum
The light has to pass through in a way that the colors are separated and refracted, but if they pass through glass and are not refracted in a certain way they will not separate the spectrum
Because the spectrum of the star's light can be seen to have dark lines all the way through, and each element has its own set of dark lines in the star's spectrum.
