Depends on where you are. Each nation has its own rules.
There are legal frequencies in the 125 KHz, 13.56 MHz, 800-950 MHz, and 2.4 MHz bands. Higher frequencies are coming.

Is ultrasonic wave radio frequency?
ultrasonic wave is sound frequency
What is the wave width of an FM radio wave?
2(frequency deviation+signal frequency)
The main difference between a radio wave and a light wave is?
The difference between a radio wave and a x-ray is the fact that x-rays have a much higher frequency. Since higher frequency means more energy in electromagnetic waves, x-rays can be used for purposes such as taking photos of things inside the body. Radio waves are at a lower frequency and have a much longer wavelength. They are used in radio, television, and communication.
What is a radio wave's relative wavelength and frequency is?
The wave length and frequency of course vary, the frequency ranges from 3kHz to 300 GHz. The wavelengths are longer than infrared.
What is the frequency of this am radio wave in hertz when An AM radio station broadcasts news at 687 kHz?
For any wave, frequency x wavelength = speed (of the wave). In this case, convert the kHz to Hz, then divide the speed of light by this frequency. The speed of light should be in meters/second. The answer will be the wavelength in meters.
What is an rfid chip?
The RFID chip is a Radio Frequency IDentification chip. When it receives a radio wave in the right frequency range, it sends back a characteristic radio signal which allows it to be specifically identified, much like a bar code would when optically scanned.
Is ultrasonic wave radio frequency?
ultrasonic wave is sound frequency
How is a radio wave different from a gamma wave?
Radio waves are lower frequency.
How does frequency of a wave compare with the frequency of the source?
The frequency of a radio wave compares to the frequency of the vibrating electrons that make it because the frequency of a radio wave is proportional to the frequency of the vibrating electrons that make it.
What is the wave width of an FM radio wave?
2(frequency deviation+signal frequency)
Who has a lower frequency gamma ray infrared wave radio wave or visible light?
Gamma ray
What electromagnetic wave have the lowest frequency?
Radio Waves.
What is the wave frequency of an FM radio wave?
FM radio is transmitted anywhere in the spectrum of 88Mhz to 108Mhz
What are the components of a radio wave?
Speed, wavelength and frequency.
Relate energy of radio to frequency of wave?
Energy of radio signal E = hf, Planck's constant times the frequency.
A radio wave has a wavelength of 0.3 m and travels at a speed of 300000000 ms. What is the frequency of this wave?
The frequency is 1000000000 Hz.
The specific frequency at which a radio operates is called?
carrier wave
