The full range is called the "electromagnetic spectrum".
No number can be given, because there's no such thing as the longest
or shortest wavelength (lowest or highest frequency). The electromagnetic
spectrum has no ends.
It would probably be em waves
The speed is constant, at least for EM waves in a vacuum. The speed will still be approximately the same in other media, e.g. in glass. Different waves can have different frequences or wavelengths, but the speed will be the same.
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)
EM spectrum consists of visible and invisible part of the spectrum. wavelength of visible spectrum is from 400nm to 700nm. nm is nano meter, 1/1000000000th of a meter. 400nm is for violet rays and 700nm is the range of red rays. yellow, orange green will be in between. EM wave is usually represented from gamma rays (10*-12) m. Picometer range to radio waves that is around 1000m wavelengths. If it is exam question, please draw a spectrum n show the range naming the waves like gamma rays, x rays, ultraviolet, violet to red , infrared, microwave and radio waves. if u wish to learn more interesting physics facts please subscribe to PhysicsFusion-sm3tr hope this helps.
Usually with electromagnetic waves, the frequency and energy is opposite to the wavelength. An EM wave such as radiowaves have huge wavelengths, slow frequencies and small amounts of energy. An EM wave such as X-rays have tiny wavelengths, fast frequencies and large amounts of energy.
Gamma rays down to Radio waves, basically the entire EM spectrum.
It has wavelengths very roughly in the octave between 350 and 700 nanometers.
We would call that "radio" waves. It's radiation (or current in the cable) with frequencies between roughly 54 to 800 MHz. (Wavelengths between roughly 37 centimeters to 5.5 meters.) Not all of this range is allocated to TV, but all TV falls somewhere in this range.
It would probably be em waves
you see how close the wavelengths are-- the closer, the more powerful it is. Here are the wavelengths- from least powerful to most powerful: Radiowaves, Microwaves, Infared Waves, Visable Light, Ultraviolet, X-rays, and Gamma rays.
Radio stations that broadcast in the AM to FM range transmit EM waves known justly as radio waves (EM waves with frequencies from 30 KHz to 300 MHz, or wavelengths from 10 km to 1 m).
EM rays which are in the range of visible light.
The speed is constant, at least for EM waves in a vacuum. The speed will still be approximately the same in other media, e.g. in glass. Different waves can have different frequences or wavelengths, but the speed will be the same.
EM waves with the shortest wavelengths are called gamma rays. The range of wavelengths that are called gamma rays is between 1 x 10^-12 meters and 1 x 10^-20 meters, or; .000000000001 m to .00000000000000000001 m .
EM spectrum involves all radiations of different wavelengths. This has been very useful in studying various things in the field of science. Certain range of wavelengths are also very important in critical analytical techniques.

Humans can see EM-radiation at the visible range. It is between the wavelengths of 400 nanometer(violet) - 700 nanometer(red).
