By definition.
Yes, very much so. Visible light waves are around 0.000001 - 0.00001m (or 10 to the power -5 to 10 to the power -6 metres). Gamma rays are much shorter, 0.0000000000001 metres (- 10 to the power -12 metres ) or shorter - or in other words, you could place between 1 and 10 million gamma waves in the space of one visible light wave.
The electromagnetic (EM) spectrum is the range of all possible electromagnetic radiation. The "electromagnetic spectrum" (or just spectrum) of an object is the characteristic distribution of electromagnetic radiation from that object. In 1900. Paul Ulrich Villard discovered another radiation, much more penetrating and able to pass even through a thick steel plate. This component proved to consist of electromagnetic waves which Rutherford called gamma-rays. They were the last editions to the electromagnetic spectrum as is known today. Paul Villard recognized them as being different from x rays because the gamma rays had a much greater penetrating depth. He had discovered they were emitted from radioactive substances and were not affected by electric or magnetic fields. These came to be called gamma rays by another scientist, Ernest Rutherford. It wasn't until 1914 that Rutherford showed that they were a form of electromagnetic (EM) like light only with a much shorter wavelength than x rays. Now we know that gamma rays are a form of EM radiation similar to x rays. Gamma rays tend to have a higher energy and a shorter wavelength than x rays do. However, the dividing line between these two forms of radiation is not clearly defined. Gamma rays or gamma-ray are forms of electromagnetic radiation (EMR) or light emissions of a specific frequency produced from sub-atomic particle interaction, such as electron-positron annihilation and radioactive decay; most are generated from nuclear reactions occurring within the interstellar medium of space. Gamma rays are generally characterized as EMR, having the highest frequency and energy, and also the shortest wavelength, within the electromagnetic radiation spectrum, i.e. high energy photons. Due to their high energy content, they are able to cause serious damage when absorbed by living cells.
Of course not. The only thing on Earth that produces gamma rays is the nuclear
decay of radioactive materials ... we don't know how to design or build anything
that generates them, and exposure to them is hazardous to your health. But TV
signals can be generated by any Tom, Dick, or Harry businessman who wants a
license to print money and can get an FCC license. Exposure to these is also
hazardous to your health, but the damage is a lot more subtle, and they're very
easy to generate and control.
Gamma rays, x-rays, and ultraviolet rays have wavelengths shorter than visible light.
yes...theyre about 0.01 nano meter
We know that ultraviolet light, X-rays and gamma rays have wavelengths shorter than visible light.
No, gamma rays have the highest energy of all the waves in the Electromagnetic Spectrum.
The gamma ray has the shortest wavelength (and shortest period) as well as the highest frequency (and highest energy) of all forms of electromagnetic radiation.That's the part of the spectrum that we call "gamma rays".There is no definite answer to this as we can have shorter and shorter wavelengths from a value which we have assigned to be the shortest wavelength.However, gamma rays have the shortest wavelength in the electromagnetic spectrum.Gamma radiation ;)The region of the spectrum that we call "gamma rays" has.
Because that term is the name we have given to electromagnetic radiation with the highest observed frequency. If they had lower frequency, then we would call them by another name. And if they're called by that name, then they must be rays of the highest observed frequency, all because that is how we have defined them.
There's a considerable (overlapping) range of frequencies for both gamma rays and cosmic rays, but the upper reach for gamma rays is considered to be higher than that for cosmic rays, all the way to 10^30Hz.

because they all travel at the same speed (speed of light)
No, gamma rays have the highest energy of all the waves in the Electromagnetic Spectrum.
Gamma rays have more energy than visible light rays. Visible light has a longer wavelength. Gamma rays have a shorter wavelength and higher frequency, and have the most energy of all electromagnetic radiation.

Yes, radio waves have a longer wavelength than visible light. They are part of the electromagnetic spectrum.

And if they're called by that name, then they must be rays of the highest observed frequency, all because that is how we have defined them.

Gamma rays are electromagnetic rays and thus have no charge or mass.
Radio and microwaves are longer than visible light. So are heat (infrared) waves. Ultraviolet waves are shorter than visible light. So are X-rays and gamma rays.
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.
Radio and microwaves are longer than visible light. So are heat (infrared) waves. Ultraviolet waves are shorter than visible light. So are X-rays and gamma rays.
