Radio waves have several uses and benefits and are not simply limited to the regular radio that comes to mind. Besides being utilized for transmitting television and sound signals, radio waves are used for transmitting data using coded form. Find other benefits of radio waves here below.
Radio waves benefit astronauts through enabling them to stay in touch with their counterparts on earth while they are on the moon. These waves also carry critical information from all space probes. Moreover, radio waves provide enhanced audio volume and clarity. Cordless and cellular phones are essentially radio transceivers. This means that they utilize radio waves from transmitting the calls. Most telephone calls are generally relayed using radio instead of wires. Some are even sent through radio waves to the relay satellites.
2. Better navigation
Radio waves have enabled better navigation of aircrafts and ships. For instance in the radar form, it is used for sending signals and then receiving them from their reflections. Radio waves sent from GPS satellites can be used by receivers for an exact indication of location. GPS systems are installed in most vehicles to provide the users with a map at all times. This technology was arrived at because of radio waves.
4. Increase accuracy
By using radio waves, we now have the capability of monitoring and control certain industrial environments. Usually, a wastewater facility requires controlling several tanks that are located on different sides of one highway. These tanks also need to relay information back to the main control system. Previously, trenches had to be dug and cables were placed to acquire the signals. This was a very expensive affair. However, thanks to radio waves, the signals can be cheaply acquired and also more accurately.
In short, radio waves are highly beneficial as they improve accuracy and allow data transmission over long distances.

Whatever the wavelength is will depend on the type of transmitter you will use. Stars, sparks and lighting also give off different types of transmitter. When you hear your radio station get fuzzy it is being interfered by these transmitters.
An ÃƒÂ¢Ã¢â€šÂ¬Ã…â€œAtlantic 252ÃƒÂ¢Ã¢â€šÂ¬Ã‚Â has about a 1 to 2 km in wavelength. People call this a long wave compared to others.
The radio, like AM stations are used for radio stations. The wave is about 100m in wavelength. This is about a medium wave
If you have a large amount of radio waves people say it can cause disorders like cancer, leukemia. They say that if you have power cabled above, or near your home it can affect your health.
