There are no limits to the E&M spectrum.
At the upper end, gamma rays extend to frequencies so high that their wavelengths are
shorter than an atomic nucleus. Higher-energy sources in the universe produce gamma
rays with higher frequency, and there's no theoretical limit.
At the lower end, the power grid radiates plenty of electromagnetic energy at 60 Hz, and
it's relatively easy to build an oscillator on your work bench, if you want to, with a frequency
of 1 cycle per month or lower. Again, there's no theoretical limit.
The energy of EM radiation depends on its frequency, and the lowest frequency corresponds to the lowest energy. Radio waves are at the low end of the energy and frequency spectrum.
The highest frequency is gamma rays And the lowest is radio waves
The highest frequency electromagnetic waves are gamma rays, which have wavelengths shorter than 10 picometers. The lowest frequency electromagnetic waves are radio waves, which have wavelengths longer than 1 millimeter.
-- The lowest frequencies that we have a name for are what we call "radio" waves. -- The highest frequencies that we have a name for are what we call "gamma" rays. Although there is not upper or lower limit in the electromagnetic spectrum.
Radio waves have the lowest frequency among electromagnetic radiations.
I don't think there is a limit, as to how high the frequency can get. The EM waves of the highest energy (and frequency) are called "gamma rays".
Gamma rays have the highest energy on the electromagnetic spectrum. They have the shortest wavelength and highest frequency, carrying the most energy of all electromagnetic waves.
The highest frequency in the electromagnetic spectrum is found in gamma rays. These rays have the shortest wavelengths and the highest energy levels of all electromagnetic waves.
The categories of the electromagnetic (EM) spectrum, in the ascending order of their frequencies are:RadioMicrowaveInfraredVisibleUltravioletX-rayGammaHence, Radio waves have the lowest frequency and the longest wavelengths while Gamma rays have the highest frequency and the shortest wavelengths.(check related link for an image)
The highest frequency part of the electromagnetic spectrum is gamma rays. Gamma rays have the shortest wavelengths and highest energy of all electromagnetic waves.
Gamma rays have the highest frequency ranging from 5 x 1022 to 3x 1019 Hz.
The seven types of electromagnetic waves, in order of increasing frequency, are radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Each type of wave has a unique wavelength and frequency, with radio waves having the longest wavelength and lowest frequency, while gamma rays have the shortest wavelength and highest frequency.
