They're found everywhere.
When you consider that radio waves are sent out by every radio or TV station,
every police or fire walkie-talkie, taxicab dispatcher, Bluetooth device, cordless
telephone, garage door opener, cellphone, and smartphone in the world, you
start to realize that no matter where you are, the room you're sitting in right
now is bathed in the radio waves from a million sources or more.
The radio wave from the space are mostly released by stars and other matters in the sky and most likely when they are emitting energy .
For example , although hydrogen emits no light , it does emit energy at a specific wavelength in the electromagnetic spectrum .
Radio waves are from "about" 1 Megahertz to 1 Terahertz. There is no hard definition of "radio wave".
Approximately 10^3 m
no, mechanical waves are not radio waves
Radio waves ARE electromagnetic waves.
Radio waves are electromagnetic waves. The radio waves have the longest wavelengths in the electromagnetic spectrum. A radio wave has a much longer wavelength than does visible light. We use radio waves extensively for communications.
Radio waves were discovered before the radio was invented.
Radio waves and cell phones
Transverse waves occur when the particles of the medium move perpendicular to the direction of the wave. In these waves, the vibrations are up and down, side to side, or in any direction perpendicular to the wave's direction of propagation. Examples of transverse waves include light waves, water waves, and seismic S-waves.
Waves can occur in any liquid. Waves can also be propagated through rock, during an earthquake, and the same mathematics that describes water waves also describes waves in electromagnetic energy such as light or radio.
no, mechanical waves are not radio waves
Radio waves ARE electromagnetic waves.
Radio waves are transverse waves. This means that the oscillations of the waves are perpendicular to the direction of energy transfer.
No. Radar waves are one category of radio waves. Think of all the radio waves that are all around you right now . . . AM radio, FM radio, police and fire radio, highway patrol radio, taxi radio, television picture and sound radio waves, cellphone radio waves, garage-door-opener radio waves, bluetooth radio waves, WiFi waves, microwaves ... and you can't see any of them ! Radar waves can easily be there in the group.
by changing the amplitude or frequency of the radio waves.
Radio waves are electromagnetic waves occurring on the radio frequency portion of the electromagnetic spectrum.
Radio Waves - radio station - was created in 2010.
by changing the amplitude or frequency of the radio waves.
Radio and light waves are electromagnetic waves, sound waves are not.
Radio waves are electromagnetic waves. The radio waves have the longest wavelengths in the electromagnetic spectrum. A radio wave has a much longer wavelength than does visible light. We use radio waves extensively for communications.
