Grating Spectrometer

A grating spectrometer is a scientific instrument used to analyze light by separating it into its individual colors or wavelengths. It uses a component called a diffraction grating, which has many closely spaced lines that diffract incoming light into different directions based on wavelength. When light passes through or reflects off the grating, it splits into a spectrum, allowing scientists to identify and measure the specific wavelengths present. This technique helps in understanding the composition, properties, and behaviors of various materials, gases, or stars by studying their light signatures in detail.
