The Earth's powerful magnetic field helps to deflect cosmic rays away from us; the atmosphere also provides a significant shielding effect from cosmic rays, by absorbing their energy in collisions. Note that we are not shielded from 100 percent of all cosmic rays, we do experience a certain amount but this is generally deemed not to be a significant health risk. Certain highly sensitive electronics are deliberately hardened further by additional shielding, particularly for space applications since the exposure increases with altitude.

The electromagnetic waves with the highest energy are?

Gamma rays--powerful enough to melt your face off. Ouch. The Earth's electro-magnetic shield, generated by a molten, spinning magnetic core, can protect us from most of the sun's radiation, but it draws the line at gamma rays.


What is gamma ray wave?

Gamma-rays are the most energetic form of light and are produced by the hottest regions of the universe. They are also produced by such violent events as supernova explosions or the destruction of atoms, and by less dramatic events, such as the decay of radioactive material in space. Things like supernova explosions (the way massive stars die), neutron stars and pulsars, and black holes are all sources of celestial gamma-rays.A gamma ray is a packet of electromagnetic energy--a photon. Gamma photons are the most energetic photons in the electromagnetic spectrum. Gamma rays (gamma photons) are emitted from the nucleus of some unstable (radioactive) atoms.Gamma rays are an extremely high-energy form of electromagnetic (EM) radiation. Gamma ray radiation has a much, much shorter wavelength than visible light, so gamma ray photons have much, much higher energies than photons of light do. Gamma rays lie at the extreme high-energy end of the electromagnetic spectrum. X-rays, which have slightly lower energies than gamma rays, are the neighbors of gamma rays along the EM spectrum. In fact, the spectral ranges of hard X-rays and gamma rays overlap. Gamma rays have wavelengths of about 100 picometers (100 x 10-12 meters) or shorter, or energies per photon of at least around 10 keV. This type of electromagnetic wave oscillates with a frequency of 3 exahertz (EHz or 1018 hertz) or higher.There is no sharp distinction between the highest energy X-rays and the lowest energy gamma rays. The distinction between X-rays and gamma rays is actually based on the origin of the radiation, not on the frequency or wavelength of the electromagnetic waves. Gamma rays are produced by nuclear transitions, while X-rays are the result of accelerating electrons. Photons with energies between about 10 keV and a few hundred keV can be either hard X-rays or gamma rays.These waves are generated by radioactive atoms and in nuclear explosions. Gamma-rays can kill living cells, a fact which medicine uses to its advantage, using gamma-rays to kill cancerous cells. Gamma-rays travel to us across vast distances of the universe, only to be absorbed by the Earth's atmosphere. Different wavelengths of light penetrate the Earth's atmosphere to different depths.


What are negative facts about gamma rays?

Gamma radiation has a very short wavelength. This is dangerous to us soft-tissued mammals because our body's natural defenses (like our skin) are unable to keep the radiation out. Gamma radiation has been linked to cancer under the assumption that our cells, once exposed, can be mutated into a cancerous cell.


What are there common uses of gamma rays?

gamma rays contributed to the creation of the atomic bombs by using the gamma radiation somehow. also gamma rays kill cancer cells during chemo or radiation therapy. -To sterilise surgical instruments.-Killing harmful bacteria-To detect brain and heart abnormalities


What is the difference between radio and gamma radiation?

They are both electromagnetic energy, so it that light (he, he) they are the same. But the gamma rays are of much higher frequency, and that means shorter wavelength and higher energy. As we move up the electromagnetic spectrum from light, we go to ultraviolet (UV) light, X-rays and then gamma rays.

What type of electromagnetic wave does the core of the earth protect us from?

The earth's magnetic field protects us and the earth from things such as solar winds and cosmic particles/radiation as well as solar radiation. Essentially, the magnetic radiation protects us from all harmful waves, varying from infrared rays to gamma rays.


Can gamma rays hurt us?

Yes. Gamma rays hurt us because they penetrate our skin. They can also be used to cure cancer(chemotherapy).

What are 3 types of harmful waves that our atmosphere protects us from?

The atmosphere protects us from harmful waves, including ultraviolet (UV) radiation, X-rays, and gamma rays. The ozone layer absorbs most of the sun's UV radiation, preventing skin damage and other health issues. X-rays and gamma rays, which are more energetic and can penetrate tissues, are largely absorbed by the Earth's atmosphere before reaching the surface, safeguarding life on Earth. This protective barrier is essential for maintaining a stable environment for living organisms.
