- Gamma rays are light (photons), not particles. They have the highest frequency and shortest wavelength on the electromagnetic spectrum. Mostly, gamma radiation results from nuclear reactions.

A sample of gamma ray-emitting material that is used for irradiating or imaging is known as a gamma source. It is also called a radioactive source, isotope source, or radiation source, though these more general terms also apply to alpha and beta-emitting devices.

- What Different Types of Light Tell Us
The electromagnetic spectrum describes all of the kinds of light, including those the human eye cannot see. In fact, most of the light in the universe is invisible to our eyes. The light we can see, made up of the individual colors of the rainbow, represents only a very small portion of the electromagnetic spectrum. Other types of light include rad...
Light travels in waves, much like the waves you find in the ocean. As a wave, light has several basic properties that describe it. One is frequency, which counts the number of waves that pass by a given point in one second. Another is wavelength, the distance from the peak of one wave to the peak of the next. These properties are closely and invers...
To study the universe, astronomers employ the entire electromagnetic spectrum. Different types of light tell us different things. Radio waves and microwaves, which have the lowest energies, allow scientists to pierce dense, interstellar clouds to see the motion of cold gas. Infrared light is used to see through cold dust; study warm gas and dust, a...
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.
Jul 16, 2020 · Light with really short, high-energy waves can be gamma rays and X-rays (used in medicine). Long, low-energy waves of light fall in the radio and microwave part of the spectrum. Electromagnetic radiation includes waves that are bigger than the largest buildings and waves that are smaller than the tiniest particles known.
Aug 29, 2023 · Gamma Rays. The part of the electromagnetic spectrum with the longest wavelength and lowest frequency is radio. The portion with the shortest wavelength and highest frequency is gamma radiation. Visible light, which is the portion of the spectrum that we can see, is roughly in the middle.

Nov 14, 2014 · Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons , each traveling in a wave-like pattern at the speed of light .
