At a high enough power density, the amount of RF absorbed by human tissue may
heat the tissue enough to damage it. Consider what a few hundred watts of RF for
a few minutes can do to the leftover meatloaf in the 'microwave' oven.
no, mechanical waves are not radio waves
Radio waves ARE electromagnetic waves.
Transverse. Radio waves are electromagnetic waves, which are transverse.
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.
No, electromagnetic waves that are felt as heat are called infrared waves, not radio waves. Radio waves have lower frequencies and longer wavelengths than infrared waves.
Radio waves were discovered before the radio was invented.
