Modulation doesn't create radio waves. After a radio wave has been created
by an "oscillator" circuit, modulation may be used to add information to it, in
some way that someone else will understand when he receives the radio signal
and will be able to recover the information with which it's been modulated.

How is radio waves used in everyday life?
to send radio waves through the air to make the radio work
Where is amplitude modulation used?
we have two types of signals namely the message signal and the carrier signal. so if the amplitude of the carrier is varied in accordance with the instantaneous value of the message signal then it is known as the amplitude modulation.if we want to transmit our message signal to long distances we need to do modulation and hence amplitude modulation is done. by amplitude modulation we generate side bands which consists of the part of the message which signal which is demodulated at the receiver to get back the original message signal we are using this amplitude modulation in radio communication. It will work in the traffic also with out disturbances but frequency modulation didn't work without disturbances.
How does walkie talkie work?
it uses radio waves
How does am and FM station work?
Both AM and FM radio operate in signal waves. Picture a beach. The ocean waves on this beach come in very regularly at 1000 waves every hour exactly, and every wave is exactly 5 feet high. AM (Amplitude Modulation) and FM (Frequency Modulation) have something in common and something different. Can you guess what those things are? They're right in the names. They both have "modulation" in common. Modulation is, in a nutshell, a change. Our beach needs some sort of change in the waves to carry a message. A change is needed in order to produce a sound on a radio, and that change can be done in two different ways: Oo! Oo! Can I guess the first one? Amplitude! Amplitude is the height of our beach waves. On our beach, we notice that some of the waves are getting lower and higher than the 5 foot waves we are used to seeing. Some of them are tiny 6 inch waves and others are huge 20 foot monster waves. On an AM radio, tiny radio waves will produce a small sound and the high radio waves produce a loud sound. The waves always come in 1000 waves per hour (or frequency) on AM Beach, and a radio set to receive a certain station will pick up only a certain frequency of waves. Let's relax on FM beach. Again, normally we have exactly 1000 waves per hour and exactly 5 foot swells. Now we notice that the waves are coming in more frequently or less frequently than 1000 per hour. Sometimes 900 waves per hour and sometimes up to 1100 waves per hour. But the waves are always 5 feet tall. Now we've changed or modulated the frequency. A lower frequency will produce a small sound in FM radio, and a higher frequency will produce a louder sound. AM has the advantage of a larger transmission distance, and FM has the advantage of more clarity.
How does downloading information through WiFi work?
Radio waves.
How does Xbox wireless controller work?
Off Radio Waves.
How do radio telescope operate?
As far as I know, there is no "optical radio telescope". There are, separately, optical telescopes (which work with visible light), and radio telescopes (which work with radio waves).
How does an ultra sound work?
By creating an xray using sound waves.
How does microwaves travel to make a phone work?
They travel just like the radio waves that make your car radio work. They are sent from a transmitter - and picked up by your phone - the phone sends radio waves back to the transmitter to complete the circuit.
What do cell phone and radar both work using?
Radio waves
Through which type of wave do mobile phones work?
radio waves
Why does your radio only work in park or neutral?
The radio waves don't follow the car when it is moving fast.
