What is another word for diffraction grating?
Pronunciation: [dɪfɹˈakʃən ɡɹˈe͡ɪtɪŋ] (IPA) 
A diffraction grating is a type of optical component that splits light into its constituent wavelengths. There are several synonyms for this term that can be used interchangeably depending on context. These include diffraction prism, optical grating, spectral grating, and dispersive grating. Diffraction prisms are often used in spectroscopy and are composed of a prism with a surface that is coated or etched with a series of parallel lines. An optical grating is a periodic structure with narrow slits that can diffract light waves, while spectral gratings are used in spectrometry to split light into its constituent wavelengths. Dispersive gratings are designed to scatter light in a specific direction and are used in applications such as telecommunications and laser technology.
