Description of Radio Waves

The radio waves have the longest wavelength in the electromagnetic spectrum. They range from the length of a football to larger than our planet. They are 1-2 km in wavelength.

The VHF stands for very high frequency and it is about 2m. The UHF stands for Ultra high frequency and that is for less than a minute.

They are used for Police radio communications, television transmissions and military air craft radios.

The velocity in a vacuum is (3x10^8 m/s)

Everyday Applacations

The most common way that radio waves are used is to transfer information. A radio is and example of that. Ships that use radar are another example of radio waves use in everyday event. Another use of radio waves is in cell phones. Cell phones use radio waves to call from one phone to another.

Health Impacts

Claims that cell phones promote “radio wave Sickness” have propganted through society for years. Associate illnesses include multiple sclerosis depression, autism, and sother ailments.(CLAIMS SAY THIS ISNT FOR SURE)

Interesting Article

Radio waves are larger than optical waves. Many astronomical emit radio waves, but that wasn’t discovered since 1932. Radio waves are also used in car engines with the spark plugs. Radio waves are also found in radio telescopes. Radio telescopes are dishes made out of conducting metal that reflect radio waves to a focus point. The wavelengths of radio light are so large, a radio telescope must be physically larger than an optical telescope to be able to make images of comparable clarity. http://science.hq.nasa.gov/kids/imagers/ems/radio.html
