no, mechanical waves are not radio waves
Radio waves ARE electromagnetic waves.
Radio waves do not emit visible light. Only light with wavelengths of roughly 4*10^-7 to 7*10^-7 meters are visible.
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 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.
Radio waves do not emit visible light. Only light with wavelengths of roughly 4*10^-7 to 7*10^-7 meters are visible.
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.
No, you can't see either of those.
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.
