RADIO WAVES

HOW RADIO WAVES ARE CREATED

• Naturally occurring radio waves are usually created by lightning
• They can also be created by other astronomical objects
• Radio waves are also made by transmitters

RADIO WAVES IN REAL LIFE

• Radio waves are used for things such as radar, radio, cellphones, and television
• Televisions use radio waves to transmit signals and along side radio, transmit sound waves as well.
• Radar uses radio waves to pick up signals and picking up reflections of objects in their path

OTHER APPLICATIONS

• Long-range Radio waves are used to communicate with astronauts up in space and carry information from space probes as they travel to distant planets

RADIO WAVE DANGERS

• Large doses of radio waves are believed to cause disorders such as leukemia and cancer

WAVELENGTH AND FREQUENCY

• The wavelength of radio waves ranges from 1 millimeter to 100 kilometers
• The frequency range of radio waves is from 3kHZ to 300 gHZ

INTERESTING FACT

• Heinrich Hertz created the first electromagnetic wave
• As a result, the unit of measurement of a radio wave was named the Hertz in his honor

WHAT THE FUTURE HOLDS

• There isn't a very clear future on radio waves as far as we have researched
• The hopeful result is that radio waves in this day and age can go past the current range of 62 miles
• All that can really be done is working harder on transmitters to get longer distances
