Diffraction grating
A diffraction grating is an optical device that disperses light into its component colors or wavelengths. It consists of many closely spaced lines or grooves, which can be made of glass or metal. When light passes through or reflects off the grating, it bends or "diffracts" at different angles depending on its wavelength. This creates a spectrum, similar to a rainbow, allowing us to see the different colors of light. Diffraction gratings are widely used in scientific instruments, such as spectrometers, to analyze the properties of light and identify substances.

A diffraction grating is an optical device used to separate light into its component colors or wavelengths. It consists of a surface with many closely spaced slits or grooves. When light passes through or reflects off the grating, it bends and spreads out, creating a spectrum. This phenomenon occurs because different colors of light travel at slightly different angles. Diffraction gratings are widely used in science and technology, such as in spectrometers to analyze materials, or in lasers to produce specific light wavelengths. Essentially, they help us understand and study the behavior of light.
