What is spectrum meaning?

Spectrum is a term used in science and mathematics to refer to a range of values or a continuum of different wavelengths, frequencies, or energies. It is often used to describe the range of electromagnetic radiation, which includes visible light, radio waves, microwaves, infrared radiation, ultraviolet radiation, X-rays, and gamma rays. Each type of electromagnetic radiation has a unique range of wavelengths and energies, and when these are plotted on a graph, they form a spectrum. In modern physics, the term spectrum is also used to refer to the distribution of energy levels in a system, such as the spectrum of electrons in an atom or the spectrum of vibrations in a molecule. Spectrum analysis is a useful tool in many scientific fields, including astronomy, chemistry, and physics, as it allows scientists to measure and analyze the properties of waves and particles.
