radioisotope
Yes and no, alpha particles are a form or radiation (a helium nucleus), they are emitted from an unstable radioactive element which decays (and turns into some lighter element) by emitting the alpha particle. This form of decay is called alpha decay.
When an isotope does not undergo radioactive decay, it is considered stable. Stable isotopes have a balanced ratio of protons and neutrons in their nuclei, which prevents them from emitting radiation over time.
This radiation can be called protonic.
neutron star has been observed at the center of a supernova remnant, known as the Crab Nebula. This neutron star, also called a pulsar, spins rapidly, emitting beams of radiation that are observed as pulses by astronomers.
LEDs can also be designed to emit light in the infrared spectrum, but the radiation emitted is very slight and only has limited use, such as communication between electronic devices using infrared ports and signals. Since the diodes are so small, they cannot easily be used to generate large amounts of heat. Other LEDs fall in the visible light spectrum, with some nearing ultraviolet light.
When a solid is heated, it emits electromagnetic radiation called thermal radiation. An example of this is when the element of a stove burner heats up and glows red hot, emitting visible light as thermal radiation. This phenomenon is governed by Planck's law of blackbody radiation.
The process in which nuclei lose energy by emitting radiation is called radioactive decay. This process can involve the emission of alpha particles, beta particles, gamma rays, or other forms of radiation.
Radiation?
Radioactive means that an atom is unstable and undergoes radioactive decay, emitting radiation in the form of particles or electromagnetic waves. This process can result in the release of energy and transformation of the atom into a different element.
Yes and no, alpha particles are a form or radiation (a helium nucleus), they are emitted from an unstable radioactive element which decays (and turns into some lighter element) by emitting the alpha particle. This form of decay is called alpha decay.
This is a radioactive chemical element.
YES
The trapping of longwave radiation in the atmosphere is known as the greenhouse effect. This process involves certain gases, such as carbon dioxide and water vapor, absorbing and re-emitting infrared radiation, which helps to warm the Earth's surface.
This process is called radioactive decay. Unstable atoms, also known as radioactive isotopes, undergo decay by emitting particles (such as alpha or beta particles) or electromagnetic radiation (such as gamma rays) in order to achieve a more stable configuration.
When something moves faster than the speed of the wave it is emitting, it creates a phenomenon called "Cherenkov radiation." This radiation manifests as a blue glow and occurs when an object travels through a medium at a speed greater than the speed of light in that medium, such as in certain nuclear reactions or particle accelerators.
The question is not very precise, so there could be a couple of answers you are looking for. If you mean what is the name of the process by which heat is removed from an object by emitting electromagnetic radiation then the answer is thermal radiation. Wikipedia has a fairly useful article of that title.
Light Amplification by Stimulated Emission of Radiation, or Laser for short, is a mechanism for emitting light within the electromagnetic radiation through a process called stimulated emission.A more detailed report can be found here:http:/en.wikipedia.org/wiki/Laser
