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 wave have a low frequency meaning they also don't have much energy. Because of the lack of energy, they do not have enough power to break bonds between atoms in our bodies. Ultraviolet waves and up are the only ones capable of doing this.
It can cause violent vibrations on the microscopic scale - like cooking your bodys cells and tissues, causing them to mutate - cancers, tumors, etc. But the medical evidence is not conclusive, Not all doctors agree about this.
-- The room you're sitting in right now is filled with radio waves from at least a million
transmitters. I am not exaggerating. If they're dangerous, then we're all dead.
On the other hand . . .
-- Have you noticed what radio waves can do to a piece of meatloaf in the microwave oven ?
X-Rays lie at a different end of the electromagnetic spectrum to radiowaves.
X-Rays are very high frequency and very small wavelength. This means they are very high in energy. As a chemist I can use X-Rays to knock electrons out from low lying orbitals or cleave covalent bonds....both are very dangerous to biological systems (kinda like being shot by tiny bullets, smashing things apart such as DNA and essential proteins).
This also means we get radicals and other reactive species that will undergo unnatural reactions in our bodies (in many cases, they can be oxidising which is very dangerous in the highly reducing environment of our bodies).
If X-Rays are like tiny bullets, radiowaves are like tiny pingpong balls. You get hit by one and it's not a big deal. They will transfer some energy to you....some will pass right through you. But generally do not possess enough energy to do any major harm.
This is a very basic overview. If you want to dig a little deeper, look up 'electromagnetic spectrum' and note how the less harmful things appear on the low-energy (long wavelength) side of the spectrum...like IR and visible light as opposed to harmful radiation such as UV and X-Rays on the higher energy side.
They are too large to disrupt cellular functions, therefore they are unable to interrupt cell growth and division.
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.
Radio waves were discovered before the radio was invented.
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.

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.
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.
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.
How are radio waves formed?
