∙ 11y ago
Technically all could be used for communication. Although not all may be suited for the use. Here are a few examples:
Radio waves - short wave/long wave radio
Microwaves - Used for communication of space objects (spacecraft, satellites, radar etc)
Infra-red - Used as a wireless communication between devices like mobile phones
Ultra Violet - Butterflies use two ultraviolet signals, UV reflectance or absorbance as a communication system
X-Rays - High powered telescopes
Dont forget fibre optics for the visible part of the spectrum.

∙ 15y agoAll cellular phone networks worldwide utilize a portion of the radio frequency spectrum designated as Ultra High Frequency, or "UHF", for the transmission and reception of their signals. The UHF band is also shared with Television, Wi-Fi and Bluetooth transmission. The cellular frequencies are the sets of frequency ranges within the UHF band that have been allocated for cellular phone use.
GSM 900 use 900 MHz frequency and GSM 1800 uses 1800 MHz (1.8 GHz). These frequencies lie in

How are longitudinal waves used in communication?
All sound waves are longitudinal (compression/rarefaction) waves.
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).
How are em waves used in dentistry?
EM waves stands for Electromagnetic Waves. The EM waves used in dentistry are usually X-Rays. These electromagnetic waves go through your skin and other body tissue (don't worry it's not very harmful or bad for you). And reflect off your bones. Think of it as a camera, the X-Ray machine sends out a flash, then takes the picture. This 'picture' shows where your bones are and whats happening to them, like, are they coming out as an adult tooth? or will you need braces in a few years. That sort of thing.

Where is electromagnetic energy found?
I prefer not to use the word "stored," because EM radiation does not "store" energy -- it transfers it. The energy shifts from the electric field of the EM wave to the magnetic field of the EM wave, and then back -- repeat ad infinitem.
What types of waves are used for communication?
electromagnetic waves they are basically used by all types only some have different names and are a type of it Like wireless is : Hertzian waves (electromagnetic waves) well the elctormagnetic waves can smd!
Which electromagnetic waves are used for communication in space?
radio waves
Which type of electromagnetic waves is used MOSTLY in communication?
Radio waves.
What types of waves are found in electromagnetic spectrum for studying the universe?
The waves are called "electromagnetic waves". All types of EM waves can be used to study the Universe.
Which kinds of electromagnetic waves are used for communication?
Radio waves help people communicate with each other.
Which types of electromagnetic waves are used for radio communication?
Those are called radio waves. Also, the so-called microwaves, which are basically a type of radio waves (with a relatively high frequency and short wavelength), too.
What type of radiation is used in mobile phone communication networks?
radio waves (part of the electromagnetic spectrum)
What form of electromagnetic waves are used in smoke detectors?
There are two types of smoke detectors:Alpha particle - these do not use electromagnetic wavesPhotoelectric - these use a beam of either visible lightor near infrared electromagnetic waves
What waves that are used in radar?
Electromagnetic waves.
What transverse wave may be AM or FM?
AM and FM are modulation types, that can probably be used for different kind of waves; but they are usually applied to radio waves. Radio waves are a kind of electromagnetic waves.
Is electromagnetic radiation infrared radiation?
No, not in general. It is rather the other way around. Infrared radiation is electromagnetic radiation, and electromagnetic radiation spans multiple types of radiation, from microwaves, light, infrared, ultraviolet, radio, and more. So electromagnetic radiation could be infrared, but that is just one type of electromagnetic radiation
What waves are used in communication?
Many different types can be:sound waves in airelectrical waves in wireselectromagnetic waves (e.g. radio, microwave, infrared, visible light)etc.
