Spectra

Spectra refers to the range and distribution of different signals, colors, or energies that a source emits or reflects. In science and technology, it often describes how light, sound, or other waves are spread across various frequencies or wavelengths. For example, a rainbow displays the spectrum of visible light, showing all the colors from red to violet. In other contexts like spectroscopy, spectra help scientists analyze materials by examining these energy distributions. Overall, spectra provide a detailed fingerprint that helps identify and understand the properties of different sources or substances.
