text: Radio waves are electromagnetic waves.
text: While sound waves are a vibration of the air, radio waves are electromagnetic and a part of the light spectrum.
text: Sound waves are mechanical vibrations of air particles (which is why sound travels so much slower than light, at a speed of 767 mph), but radio waves are electromagnetic energy and a part of the same spectrum as light.
text: Radio waves are electromagnetic radiation, but they fall within the category of non-ionizing radiation, meaning they are longer and less energetic wavelengths.
text: Radio waves are electromagnetic radiations.
text: Radio waves are electromagnetic (EM) radiation at the lower end of the EM spectrum.
text: Because of this combination of fields, radio waves are also referred to as ELECTROMAGNETIC RADIATION.
text: Radio waves are electromagnetic waves.
text: Radio waves are electromagnetic waves that can travel through a vacuum.
text: The main difference between Radio Waves and Sound Waves is that Radio waves are electromagnetic waves made mainly by the vibration of electrons/charges and didn’t require a medium to travel within and Sound waves are mechanical waves using a medium (air, water, ground etc)
text: Radio waves are electromagnetic waves which carry signals through the air (or through space) at the speed of light with almost no transmission loss.
text: Radio waves, also called radio waves as they were discovered by German physicist Heinrich Hertz in 1888, are electromagnetic waves, that is to say the combined oscillation of an electric field and a magnetic field.
text: Since radio waves are electromagnetic waves and travel at 2.997 X #10^8# meters/second, then you will need to know the frequency of the radio wave.
text: In reality, radio waves are actually electromagnetic waves that are created when a magnetic field is joined with an electric field.
text: Then, when the car receives the radio waves, which are electromagnetic waves, the waves generate a current in a wire in the car, and this tells the car which direction to move in.
text: Radio waves are electromagnetic waves (light), but we can't see them.
text: Radio waves are electromagnetic waves and travel at the speed of light
text: Both radio waves and light are electromagnetic waves; their main difference is their frequency.
text: In that case radio waves could be defined as light because radio waves are electromagnetic waves with a low frequency and high wavelength .
text: Radio waves are electromagnetic waves within the frequencies 30KHz - 300GHz, and include microwaves.
text: Radio waves are the electromagnetic waves that lie in the region of 300 GHz to 3 kHz.
