Radio Waves

Backround Info On Radio Waves

1. Heinrich Hertz, a German physicist, applied Maxwell's theories which refers to the electric and magnetic fields separately to the production and reception of radio waves.

2. Radio waves are made from nuclear reactions from stars and planets.

3. Radio waves have longest wavelength they, have frequencies from 300 GHz to as low as 3 kHz, and corresponding wavelengths from 1 millimeter to 100 kilometers

1. Radio telescopes which are used to find radio waves and it's origins, astronomers can learn about distant planets, stars, and just about anything in the universe and it's composition, structure, and motion.

2. Satellite Communication, AM/FM Radios, Police Radios, Wireless Internet, and Mobile Phones.

How Radio Waves Are Used

Why Are Radio Waves Important

1. MRI ( Magnetic Resonance Imaging)
   radiology imaging that uses magnetism, radio waves, and a computer to produce images of body structures.

2. We use both our phones and Wi-Fi for on the go and everyday activities.

3. They also keep us safe because police use radios to communicate.

Future Uses For Radio Waves

1. Better navigation for aircrafts and ships.

2. Better communication between astronauts and ground control.

3. But there's more use in radio astronomy which has lead us to find out about pulsars, quasars, and radio galaxies.
