Why do emergency services use radio waves in a wavelength range that no one else is allowed to use?
They unfortunately don't ... but they try to :
to keep those frequencies clear for important messages (rather than chit-chat).
Answer 2I don't know where you come from, but in most countries it is a criminal offence to transmit or listen into a frequency you are not allowed to use, including those of the emergency services.
In order to use a frequency you need to get a licence for it from the government (with a few exceptions, for example the broadcast frequencies where you do not need a licence to listen, but do to transmit).

When was Radio Amateur Civil Emergency Service created?
Radio Amateur Civil Emergency Service was created in 1952.
What type of frequency and wavelength does radio waves have?
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.
What is the minimum wavelength of a radio wave?
Extra-low frequency radio waves can have wavelengths as long as 3.5 miles or more. The shortest wavelength is around 1 mm.
How government use ham radio?
The government may utilize ham radio (technically defined as "Amateur Radio") during times of disaster, natural or man-made, to provide inter-agency emergency communications. Amateur Radio operators by law are not allowed to accept payment for their services, and as such, they are not government employees. There are several volunteer organizations that various government agencies may enlist to provide emergency communications, such as ARES, the Amateur Radio Emergency Service. For more information on how Ham Radio can help during disasters, visit http://www.emergencyradio.org/.
What does the RACES group of the US represent?
The Radio Amateur Civil Emergency Service (RACES) was founded by the US government in 1952. It is a network of amateur radio operators that agree to provide their services in case of emergency. This can allow for faster communication than would be possible through existing government services.
Do radio waves have short or long wavelength?
Short wavelength
Is a wavelength of a radio longer or shorter than a radio 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.
What would one use an EPIRB used for?
Emergency positioning indicating radio beacons are used during emergencies. It is used to alert search and rescue services in the event of an emergency
Which electromagnetic waves has the longest wavelength?
"radio waves" have longest wavelength..
What signal has the longest wavelength?
The signal with the longest wavelength is radio waves. They have wavelengths ranging from meters to kilometers.
What is the wavelength of Radio 3 MW?
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.
What wavelength is smooth radio on?
102.2
