Radio waves have the longest wavelengths in the electromagnetic spectrum. These waves can be longer than a football field or as short as a football. Radio waves do more than just bring music to your radio. They also carry signals for your television and cellular phones

What do astronomers use to map the shape of the Milky Way?
Radio Waves
What electromagnetic wave have the lowest frequency?
Radio Waves.
What is the longest wavelengh in the electromagnetic spectrum?
The electromagnetic waves with the longest wavelength are called "radio waves". There is no limit to how long the wavelengths can be.
Do car keys use radio waves?
yes,they do use radio waves
Do walkie talkies use radio waves?
Yes. A good rule of thumb is that if the device has an antenna, it uses radio waves. An antenna would not be needed if it didn't use radio waves.
What is a radio wave?
Radio waves are electromagnetic waves. The radio waves have the longest wavelengths in the electromagnetic spectrum. A radio wave has a much longer wavelength than does visible light. We use radio waves extensively for communications.

How bad the radio waves are for people?
Not very. As far as I know there's no real evidence that radio waves cause any measurable harm to people.
What is the wavelengh of radio waves?
We use radio waves for various purposes with wavelengths between 1 millimeter and 5 kilometers.
How do humans use radio waves?
Communications over long distances are economically achieved by the utilization of radio waves.
What does a wireless network use as its transmission media?
radio waves or radio frequency
Why em waves are called as radio waves?
We have several names for E&M waves, depending on their wavelength. "Radio" is one of the names ... typically the name we use for the longest class of waves.
