👉 Spectra, also known as spectral lines, are a type of electromagnetic radiation that can be detected and classified by their wavelengths. These lines are used in various scientific fields such as spectroscopy, atomic physics, and quantum chemistry to study the properties of atoms and molecules. In spectroscopy, spectra are defined as the collection of light waves emitted or absorbed by an object during its interaction with a given electromagnetic field. Spectra can be classified into different types based on their wavelength range, frequency, and
