Spectrum (physical sciences) - Wikipedia
In the physical sciences, the term spectrum was introduced first into optics by Isaac Newton in the 17th century, referring to the range of colors observed when white light was dispersed through a prism.

Dec 16, 2024 · electromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength. Although all electromagnetic waves travel at the speed of light in a vacuum, they do so at a wide range of frequencies, wavelengths, and photon energies.
Electromagnetic Spectrum Definition and Explanation - Science …
Aug 29, 2023 · What Is the Electromagnetic Spectrum? The electromagnetic spectrum is the continuous spectrum of electromagnetic radiation. It covers an enormous frequency range, from about 1 hertz (Hz) at the extreme low end to over 10 25 Hz at the high end, with no gaps in the frequency range.
What is Spectrum: Types of Spectrum - Scienly
Nov 22, 2024 · In simple words, a series of coloured bands (wavelengths) produced when light is separated into its constituent wavelengths is called spectrum. For example, when a white light is incident on a prism, a spectrum of different colours from red to violet is observed.
15.1 The Electromagnetic Spectrum - Physics - OpenStax
Define the electromagnetic spectrum, and describe it in terms of frequencies and wavelengths; Describe and explain the differences and similarities of each section of the electromagnetic spectrum and the applications of radiation from those sections
Electromagnetic Spectrum – The Physics Hypertextbook
Infrared radiation (IR radiation) is em radiation for which the wavelengths are longer than those for visible radiation. A precise border between visible radiation and infrared radiation cannot be defined because visual sensation at wavelengths greater than 780 nm can be experienced.
