Radio waves are controlled by the people who operate transmitting devices and by the
laws of nature, not by the government.
The government controls access to the privilege of operating transmitting devices.
If that access were not controlled, the entire radio spectrum would sound like the 27 MHz
'citizen's band', and nobody would get any productive use out of it. Including would-be
police, fire, ambulance, and cellphone users.

What is a radio controlled watch used for?
Radio controlled watches use radio waves that are set by synchronizing a time code that are transmitted by a radio transmitter. These radio controlled watches are used to set and display the time accurately.
Can the Hubble Space Telescope detect radio waves?
I do not believe that the Hubble is equipped for radio astronomy. Certainly it can "detect" radio waves; it is remote-controlled by radio. But most radio astronomy is done with earth-based dish antennas.
What is the difference between a remote control car and a raido control car?
Generally remote control cars are controlled via either a cable or infared, where as radio controlled cars are strictly controlled by radio waves. However radio controlled cars can also be described as remote controlled.
Does mechinal waves have radio waves?
no, mechanical waves are not radio waves
Is remote control the same as radio control?
Not usually, remote control may be via wires, hydraulic, radio waves or smoke signals, Radio control refers specificaly to items controlled by radio.
Are radio waves transverse waves or longitudinal waves?
Transverse. Radio waves are electromagnetic waves, which are transverse.
When did Nikcola Telsa invent the radio?
As early as 1892, Nikola Tesla created a basic design for radio. On November 8, 1898 he patented a radio controlled robot-boat. Tesla used this boat which was controlled by radio waves in the Electrical Exhibition in 1898, Madison Square Garden.
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.
Can you control radio waves controlled equipment with the help of an infrared source?
If I understand the question correctly, you're basically asking if you can use an infrared remote instead of a radio remote to control a radio controlled device.Let me say that again: radio controlled device.No, you cannot. If you're an electronics engineer, you could probably substitute some kind of IR receiver for the radio circuitry, and then you'd be able to control it with your infrared remote. But at that point, it would no longer be a radio controlled device.
How are radio and television waves added to em radio waves?
by changing the amplitude or frequency of the radio waves.
What radio waves?
Radio waves are electromagnetic waves occurring on the radio frequency portion of the electromagnetic spectrum.
