First of all, your question is not worded all that well. When we speak of a wave, in this case an electromagnetic one (as opposed to one made of water perhaps), we tend to describe them quantitatively with certain numbers. One may speak of the frequency of the wave (measured in Hertz), the energy of a wave (in joules), or, in your case, the wavelength of a wave (in metres).
The electromagnetic spectrum is usually taught to span from radio waves (waves with relatively large wavelengths and low frequencies) to gamma rays (waves with relatively small wavelenths and very high frequencies). The misunderstanding you seem to have is that the electromagnetic spectrum stops at radio waves. It does not.
In theory, the electromagnetic spectrum is infinite and continuous. That is to say, there is no limit to how large a wavelength can be nor how small one can be. The electromagnetic spectrum susually stops at radio waves (with a typical wavelength ranging from 1 to 10 metres) because waves longer than these lose their practicality. In theory, they exist, but they simply are not as important to us than their shorter cousins!!!
Just as a side note, "long waves" are said to have a wavelength of around order 10^3 metres (or just around the order of a kilometre). Theoretically, I can imagine it possible to have a wave with a wavelength as long as the universe itself! Of course, as I mentioned earlier, such waves are of little practical value to us. As a result, yes it does have the "longest" waves.
What else can I help you with?
What is the minimum wavelength of a radio wave?
Extra-low frequency radio waves can have wavelengths as long as 3.5 miles or more. The shortest wavelength is around 1 mm.
What type of radiation has the shortest wavelength of radio waves or cosmic rays or ultraviolet light or infrared light?
X-rays have the shortest wavelength of those listed.
Describe the difference between radio waves visible light and gamma rays?
frequency energy wavelength
Which has longer wavelength radio or gamma?
radio waves! radio waves have wavelengths longer than about a millimeter, while visible light has wavelengths around 750 billionths to 400 billionths of a meter.
Why is microwaves found between infrared and radio waves?
the electromagnetic spectrum (all existing radiation) is organized in order of shortest wavelength from the left to longest wavelength from the right. Infrared waves, felt as heat, are slightly longer than the visible light spectrum, and microwaves longer still, and radio waves longer still.
What has shortest wavelength?
X-rays and Gamma rays. Radio Waves have the longest.
Which will have the longest wavelengths light waves X-rays or radio waves?
Of the items on that list, radio has the longest wavelength and x-rays have the shortest.
Which are the longest and shortest wavelengths?
The longest wavelength is radio waves, which can range from several meters to thousands of kilometers. The shortest wavelength is gamma rays, which are typically less than 0.01 nanometers in length.
Which waves have the longest wavelength in the electromagnetic spectrum?
The longest ones that we have a name for are the ones we call "radio waves". There are a lot of electromagnetic waves longer than that, which we don't even have a name for ... probably because we don't use them for anything much.
What happens to the electromagnetic spectrum as you move from gamma to radio waves?
As you move from gamma rays to radio waves on the electromagnetic spectrum, the wavelength gets longer and the frequency decreases. Gamma rays have the shortest wavelength and highest frequency, while radio waves have the longest wavelength and lowest frequency.
What is the ascending order of the eight electromagnetic spectrum waves base from their wavelength?
Shortest wavelength is gamma rays. Next longer wavelength is with Xrays. Then Ultraviolet, visible radiations, infra red, microwaves, radio waves with shorter wavelength and radio waves with longer wavelength
What is the longest to shortest wave length?
The longest wavelength is radio waves, followed by microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays, which have the shortest wavelength.
What is the minimum wavelength of a radio wave?
Extra-low frequency radio waves can have wavelengths as long as 3.5 miles or more. The shortest wavelength is around 1 mm.
What type of radiation has the shortest wavelength of radio waves or cosmic rays or ultraviolet light or infrared light?
X-rays have the shortest wavelength of those listed.
What waves have the shortest wavelenght?
Gamma rays are the waves with the shortest wavelength. The waves having highest frequency have the shortest wavelength. As gamma rays have the highest frequency starting from 10^19 and onwards so they have the shortest wavelength starting from 10^-11 and decreasing.
Order the types of waves from lowest frequency and wavelength to the highest?
There are many types of waves, but the main ones are: radio waves, microwaves, infrared waves, visible light waves, ultraviolet waves, x-rays, and gamma rays. Radio waves have the longest wavelength and lowest frequency. Gamma rays have the shortest wavelength and highest frequency.
Which electromagnetic waves have the longest wavelength and highest frequencies?
The longest wavelengths are usually referred to as radio waves, whereas the highest frequencies are referred to as cosmic rays (the opposite end of the spectrum).
