👉 Photospectroscopy is a type of spectroscopic technique that uses light to measure the properties of matter, such as its mass and temperature. It involves the use of a spectrometer, which consists of a device designed to measure the intensity of light emitted by a substance. The instrument can be used to determine the composition of a sample, the frequency of its absorption or emission spectra, and the wavelength at which it appears in the spectrum. Photospectroscopy is commonly used in fields such as materials
