Does mechinal waves have radio waves?
no, mechanical waves are not radio waves
How are radio waves created?
Radio waves are made by different types of transmitter. They are also given off by stars and lightning, this is why there is interference on your radio in a thunderstorm.
How are electromagnetic waves different to radio waves?
Radio waves ARE electromagnetic waves.
How did radio waves help revolutionize the state of communication?

What is a radio wave?
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.
Why were astronomers interested in studying radio waves in the 1980 and 1990?
B
What do astronomers use to map the shape of the Milky Way?
Radio Waves
What do astronomers use to study quasars?
Scientists use radio waves to study distant quasars because quasars emit large amounts of radio waves but not much visible light.
Why are radio telescopes able to operate all the time?
That is because radio waves pass through clouds so radio astronomers do not have to wait for a clear sky.
How do astronomers study the very outer regions of the universe?
radio waves. Of course they also use very big optical telescopes.
What wavelengths can astronomers detect from earth?
Only those which aren't absorbed too much by the atmosphere. Those are visible light, and radio waves.
Why do astronomers observe the galaxy at millimeter wavelength?
Millimeter wavelengths are short frequency radio waves astronomers use because they can see gases and other phenomena not visible in visible light. MM wavelengths are usually used where the air is dry so water vapor can't scatter the waves.
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.
Which kinds of electromagnetic waves are used for communication?
Radio waves help people communicate with each other.
How are electromagnetic waves different to radio waves?
Radio waves ARE electromagnetic waves.
How are radio waves created?
Radio waves are made by different types of transmitter. They are also given off by stars and lightning, this is why there is interference on your radio in a thunderstorm.
