Gamma-ray astronomy has become a rich field of research and matured significantly since the launch of NASA's Compton Gamma Ray Observatory in April 1991. Studies of the diffuse gamma-ray emission of the Galaxy can now be performed in far more detail and extended into the MeV regime, ...
Gammarays can be helpful as well as harmful(and are very unlikely to turn you into the Hulk). To destroy brain cancers and other problems, medical scientists sometimes use a "gamma ray knife." This consists of many beams of gamma rays focused on the cells that need to be destroyed. Whic...
Gamma rays are the type of electromagnetic (EM) radiation and have the highest energy content of all EM waves which range from extra low frequency waves to gamma rays. It is the high energy content that makes them dangerous and yet useful in some circumstances....
Gamma rays are a form of electromagnetic radiation, and so is the visible light that our eyes have evolved to see. All electromagnetic radiation has a wavelength and a frequency. We can see just a relatively narrow band of the electromagnetic spectrum (390 to 700 nanometers). On one side ...
The amount of energy in a light wave is proportionally related to its frequency: High frequency light has high energy; low frequency light has low energy. So, gamma rays have the most energy (part of what makes them so dangerous to humans), and radio waves have the least. Of visible lig...
Why do X-rays and gamma rays have equivalent RBE values if they provide different amounts of energy to the body? a. Penetration distance, which depends on energy, is short for both X-rays and gamma rays. b. Penetration distance, which depends on energy, i ...
The magnetic field of the sun protects the earth from cosmic or galactic cosmic rays emitted by supernova explosions, stars, and gamma-ray bursts [97]. Nevertheless, galactic cosmic rays could still reach the earth during the solar minimum, the least solar radiation energy period. In the 20th...
according toNASA Space Place. This unsettled magnetic field behavior — also known as solar activity — can trigger solar flare eruptions from the surface that release vast amounts ofelectromagnetic radiation— a form of energy that includes radio waves, microwaves, X-rays, gamma rays and visible...
What does the Ordovican mass extinction have in common with the Hulk? Gamma rays, dude. How to make your own traffic light changer. You can buy strange or wonderful things: False dog testicles. Avocado green kitchen appliances can still be had. Like, paying $36 or more for a VIRTUAL ...
25K Cathode Ray Experiments use cathode rays, invisible particle beams in vacuum tubs, to explore subatomic particle behavior. Learn about the first Cathode Ray experiment in 1897 and how the results were interpreted to prove the presence of electrons. Related...
