Radio waves aren't necessarily harmless. Radio waves, especially very short ones, can cook food; so they need to be used carefully too. Infrared can burn you, visible light can kill you, and UV is very destructive. But X-rays and Gamma rays are very short and will tear up molecules and even atoms without you knowing it. Be careful out there. Wear your tin-foil hat!
Radio waves are electromagnetic waves that carry energy. When these waves are absorbed by the radio's antenna, they induce electrical currents in the circuitry of the radio. This process allows the radio to convert the energy from the radio waves into sound, enabling us to hear broadcasts. However, radio waves themselves do not heat; it is the conversion of that energy into electrical signals that allows the radio to function.
Both radio waves and tv waves are electromagnetic waves. So both have the same speed in vacuum. Of course radio waves are of lower frequency compared to that of tv waves.
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.
because they ionize the living cells
The frequency range that the radio waves can penetrate the human body is between 1Hz and 10 KHz. This frequency of the radio waves is however not dangerous.
Microwaves are more dangerous than radio waves because they have higher frequencies and can penetrate deeper into the body, potentially causing harm to tissues and organs.

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.
Wireless routers, like phones television and radio, transmit data through radio waves. Most routers operate between 2.5 and 5 GHz. Non-ionizing wavelengths such as infra-red, microwaves, and radio waves tend to not be dangerous.
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.
