Is scientific theories ever proven?
There was once a theory, that electromagnetic waves might be used for communication over long distance. Your mobile phone is the proof that the theory was correct.
What type of electromagnetic radiation is commonly used for long-distance communications?
In technology, radio waves or microwaves are typically used.In our day-to-day communication (WITHOUT technology), we also use visible light.
What is microwave satellite communication?
It is communication with a satellite orbiting the planet using microwaves, a type of electromagnetic wave of lower frequency than light but higher frequency than radio waves. Microwaves are often used in this way as they can penetrate the earth's atmosphere, but can travel a long enough distance to reach the satellites, unlike x ray waves.
Is the electromagnetic spectrum the same as the electromagnetic wave?
No. The spectrum means the entire range of wavelengths that electromagnetic waves can have, ranging from x-rays and shorter waves right up to the kilometre-long waves used for submarine communications and long-range navigation.
What is the longest wavelengh in the electromagnetic spectrum?
The electromagnetic waves with the longest wavelength are called "radio waves". There is no limit to how long the wavelengths can be.
What was Guglielmo Marconi's most important invention?
Marconi discovered electromagnetic radiation-now generally known as radio waves, at the time more commonly called "Hertzian waves" or "aetheric waves".-WindStone :)
Why aren't ultraviolet waves not used to transmit signals to and from communication satellites?
Because they are of the highest frequencies in the known electromagnetic spectrum. This means their wavelength are very short, which means they will not travel very far, as opposed to low-frequency RF waves. In comparison, the same idea applies to vehicle taillights and why they're colored red (the color red has the longest wavelength in visible light and it will be visible even from a long distance).
What waves are apart of the electromagnetic spectrum?
Everything from long radio waves up to gamma radiation
What are the names of the wavelengths?
For electromagnetic waves: thermal radiation and radio waves are pretty long. For sound waves: bass sound waves are pretty long, so is quiet. For water waves: the tides
What are the names of the longer wavelengths?

What are electromagnetic waves with the longest wave lengths and the electromagnetic waves with the shortest wave lengths?
The longest wavelength corresponds to long wave radio, I think the longest used is about 2000 meters. The shortest are gamma rays, which occur in radioactivity, these are from about 10-11 meters down.
What are the electromagnetic waves of energy from long to short?
long medium short vhf uhf microwave
