Light energy is present in everyday life, giving people the ability to cook, listen to the radio, and see inside the human body to treat medical conditions. Discover the different types of light energy such as infrared waves, x-rays, and gamma rays. What Is Light Energy? Wow! What a...
. When combined, they makewhite light. When split, either through water droplets or prisms, their individual wavelengths become visible through their different colors. In order of increasing frequency and energy, the waves are: Radio, Microwave, Infrared, Visible, Ultraviolet,X-ray, and Gamma....
Electromagnetic radiation is emitted energy in the form of waves called electromagnetic waves, or light. According to quantum mechanics, light is both a particle and a wave. When it is being considered as a particle, it is called a photon. When it is being considered as a wave, it is cal...
Basically, an X-ray machine transmits the radiation through the body. Some of it comes out on the other side of the body (where it is exposed to a digital detector to form an image) while some of the radiation is absorbed in body tissues (which is referred to as ‘radiation dose’ a...
other observatories are instrumented to detect cosmic emitters ofradio waves, while still others calledsatellite observatoriesare Earth satellites that carry special telescopes and detectors to study celestial sources of such forms of high-energy radiation asgamma raysandX-raysfrom high above theatmosphere...
light,X-rays, andgamma rays. All of these waves travel at the same speed—namely, thevelocity of light(roughly 300,000 kilometres, or 186,000 miles, per second). They differ from each other only in thefrequencyat which their electric and magnetic fieldsoscillate....
Electromagnetic radiation, in classical physics, the flow of energy at the speed of light through free space or through a material medium in the form of the electric and magnetic fields that make up electromagnetic waves such as radio waves and visible l
Also seen at high photon energies is theCompton effect, which arises when anX-rayor gamma-ray photon collides with an electron. The effect can be analyzed by the same principles that govern thecollisionbetween any two bodies, includingconservation of momentum. The photon loses energy to the elec...
Ultraviolet radiation,that portion of the electromagnetic spectrum extending from the violet, or short-wavelength, end of the visible light range to the X-ray region. Its wavelengths are between 400 and 10 nanometers. Learn more about ultraviolet radiati
