Radio waves are electromagnetic energy, similar to light, but of much longer wave lengths.
They're man-made. Radio waves are eminated from various devices, not nature.
no, they are made up of light waves, similar to radio waves and both are in the same spectrum (the electromagnetic spectrum) but they have different wavelenghts.
No. Only of radio waves.
Marconi made alot of money by producing radio waves.
no, mechanical waves are not radio waves
Transverse. Radio waves are electromagnetic waves, which are transverse.
Radio waves ARE electromagnetic waves.
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 are made by different types of transmitter. They are also given off by stars and lightning, this is why there is interference on your radio in a thunderstorm.
