- In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light.

Sep 30, 2022 · On one end of the electromagnetic spectrum are radio waves, which have wavelengths billions of times longer than those of visible light. On the other end of the spectrum are gamma rays, with wavelengths billions of times smaller than those of visible light.
Gamma rays, X-rays, and extreme ultraviolet rays are called ionizing radiation because their high photon energy is able to ionize atoms, causing chemical reactions. Longer-wavelength radiation such as visible light is nonionizing; the photons do not have sufficient energy to ionize atoms.
In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. [4][5] In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum, and polarization.
Objects that do not give off their own visible light (and are therefore invisible to our eyes in the dark) glow in other wavelengths, like infrared or ultraviolet. The entire range of light, from radio waves to gamma rays, is known as the electromagnetic spectrum.
Jul 18, 2024 · The electromagnetic spectrum includes a range of all types of light, not just what we can see. This range – going from radio waves to gamma rays – is mostly invisible to our eyes.
Nov 14, 2024 · Light is electromagnetic radiation that can be detected by the human eye. Electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less than about 1 × 10 metres to radio waves measured in metres.
Gamma rays. These are all forms of radiation with energies much higher than visible light. X-rays and gamma rays have enough energy that during interaction with atoms, they can remove electrons. This causes the atom to become charged or ionized. That's why we refer to this as ionizing radiation.
