Why are radio waves electromagnetic?
Because they are
Are radio waves transverse waves or longitudinal waves?
Transverse. Radio waves are electromagnetic waves, which are transverse.
Why can radio waves travel through space but sound waves can not?
Radio waves travel through empty space because they are electromagnetic waves, whereas sound is a wave that must travel through air.
Are AM radio waves are an example of longitudinal waves?
No. Radio waves are a type of electromagnetic waves; electroctromagnetic waves are transverse waves.
Which waves have the longest wavelength in the electromagnetic spectrum?
The longest ones that we have a name for are the ones we call "radio waves". There are a lot of electromagnetic waves longer than that, which we don't even have a name for ... probably because we don't use them for anything much.
Was the radio named after radio waves or were radio waves named after the radio?
Radio waves were discovered before the radio was invented.
Why are radio waves electromagnetic?
Because they are
Which is stronger X-rays or radio waves?
X-rays tend to be stronger than radio waves. Rays are normally stronger because of the type of beam not a wide spreading wave and can maintain it's strength. As for a wave, since it spreads farther and longer it loses it's power/strength.
Why are satellite used to relay radio waves?
Satellites are used to relay radio waves to the other side of the world because radio waves cannot travel directly through the Earth.
Which has a higher frequencies am radio waves or fm radio waves?
FM radio has the higher frequency which is why it sounds better. AM is a lower frequency but can travel further because the waves bounce off
What is the exact temperature for radio waves?
radio waves dont have a temperature because they are comprised of energy and photons, not ordinary matter
Explain why the energy of infrared waves is greater than the energy of radio waves?
The energy of infrared waves is greater than the energy of radio waves. This is because infrared waves has a smaller wavelength compared to radio waves. The smaller the wavelength, the higher the energy.
Does mechinal waves have radio waves?
no, mechanical waves are not radio waves
Are radio waves transverse waves or longitudinal waves?
Transverse. Radio waves are electromagnetic waves, which are transverse.
How are electromagnetic waves different to radio waves?
Radio waves ARE electromagnetic waves.
Are radar waves visible?
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.
How radio waves harmful?
Radio waves are harmful to people because they give off radiation. Radiation is known to cause cancer in humans.
