500m
Commercial AM broadcast in the USA takes place in the band of 0.55 to 1.7 MHz,
corresponding to wavelengths from 176.3 to 545.1 meters.

Wavelength
One convenient working definition of 'radio' is: Electromagnetic radiation withfrequency up to 300 GHz / wavelength down to 1 millimeter.'Radio' is our name for the lowest frequency / longest wavelength, so there'sno lower limit on frequency, or upper limit on wavelength.
Extra-low frequency radio waves can have wavelengths as long as 3.5 miles or more. The shortest wavelength is around 1 mm.
Wavelength = (speed) divided by (frequency) = (300,000,000) / (60,000) = 5,000 meters
Short wavelength
That depends on what station the radio is tuned to and the other radio signal. In general, they tend to be quite similar if not identical.
"radio waves" have longest wavelength..
The signal with the longest wavelength is radio waves. They have wavelengths ranging from meters to kilometers.
The wavelength of a radio wave can be calculated using the formula: wavelength = speed of light / frequency. For a radio station broadcasting at 3 MW (megawatts), which is likely to be in the medium-frequency range, the approximate wavelength would be around 100 meters.

Wavelength
Radio waves have the longest wavelength among the types of electromagnetic radiation listed.
In the electromagnetic spectrum, it is the radio wave that has the longest wavelength. Some radio waves are over 100 yards long.
The frequency of a 150 meter radio wavelength can be calculated using the formula: frequency = speed of light / wavelength. For a 150 meter wavelength, the frequency would be approximately 2 MHz (megahertz).
