spectral resolution

Spectral resolution refers to a device's ability to distinguish between different wavelengths or colors of light in a spectrum. Higher spectral resolution means it can separate closely spaced wavelengths, providing more detailed information about an object's composition or properties. For example, in a spectrometer used in astronomy, better resolution allows scientists to identify specific elements in a star's light. Essentially, spectral resolution determines how finely a device can analyze the different "colors" or energies of light, leading to more precise interpretations of the data collected.
