Glowing gases, like that of a hot star, produces or gives off light in specific frequencies. The resulting spectrum has bright lines against a dark background and is called

• emission spectrum

• absorption spectrum

• continuous spectrum

A gas can also absorb parts of light that shine through it. This gas blocks some of the light at specific frequencies producing dark lines and is called a

• emission spectrum
