∙ 12y 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 kinds of electromagnetic waves are used for communication?
Electromagnetic waves used for communication include radio waves, microwaves, and light waves (in the form of lasers). These waves are commonly used in technologies such as radio communication, satellite communication, Wi-Fi, and fiber optic communication.
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 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.
How do you describe Elcotoromagnetic waves and name two types of electromagnetic?
Electromagnetic waves are a form of energy transmitted through a combination of electric and magnetic fields oscillating perpendicular to each other. Two types of electromagnetic waves are radio waves, which are used for communication, and visible light, which is the range of wavelengths that is visible to the human eye.
What type of radiation is used in mobile phone communication networks?
radio waves (part of the electromagnetic spectrum)
What is the electromagnetic wave which has longest wave length?
Radio waves have the longest wavelength among the electromagnetic waves. They are used for communication and have wavelengths ranging from a few millimeters to hundreds of meters.
What type of electromagnetic radiation has the smallest frequency?
Radio waves have the smallest frequency among the types of electromagnetic radiation. They have wavelengths ranging from thousands of meters to millimeters and are commonly used in communication technologies.
Electromagnetic waves with the longest wavelenght?
Radio waves have the longest wavelength among electromagnetic waves. They have wavelengths ranging from about 1 millimeter to over 100 kilometers. Radio waves are used for various communication technologies, including radio broadcasting and cellular networks.
In what ways are sound waves and electromagnetic waves different?
Sound waves require a medium to travel through, while electromagnetic waves can travel through a vacuum. Sound waves are mechanical waves that require particles to propagate, while electromagnetic waves are made up of oscillating electric and magnetic fields. Sound waves are slower than electromagnetic waves and are typically used for communication over short distances, while electromagnetic waves can travel long distances at the speed of light.
