the shortest of all rays
The shortest wave is a Gamma wave
Wavlength
Gamma rays have higher frequency than X-rays. Gamma rays have frequencies greater than 10^19 Hz, while X-rays have frequencies in the range of 10^16 to 10^19 Hz.
Gamma rays are gamma rays are gamma rays.
gamma rays
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.
A gamma ray is an electromagnetic ray, and that is how they are related. Electromagnetic rays come in a range (a spectrum) of frequencies. We could also say that they come in a range of wavelengths or energies, too. Gamma rays are produced by nuclear action (changes in atomic nuclii), and they are the electromagnetic rays at the very high end of the frequency range (and the energy range). They have the shortest wavelength, too. Below gamma rays are the X-rays, then below that ultraviolet rays. Below that are the optical or visible frequencies of light, and then below that are the infrared rays or wavelengths. Below infrared are the microwave frequencies, and below that we find "regular" radio waves.
Gamma Rays
Gamma rays have a higher frequency than visible light. Gamma rays are a form of electromagnetic radiation with the highest frequency and energy in the electromagnetic spectrum, while visible light falls in the middle range of the spectrum.
no gamma rays are the best
Cathode rays generate x-rays and gamma rays are electromagnetic radiation. Gamma rays have very high penetration power.
Gamma rays have a higher frequency than X-rays. Gamma rays are the most energetic form of electromagnetic radiation in the electromagnetic spectrum, whereas X-rays have a lower frequency than gamma rays.
