Quizplus · Accepted Answer

Both a prism and a diffraction grating can be used to spread light into its component colors in a spectroscope. Prisms work by refracting (bending) light, while diffraction gratings work by diffracting (spreading) light through a series of closely-spaced lines or grooves. Both methods result in a spectrum of colors that can be used to identify the chemical elements present in a sample.
