Applications Radio waves and Broadcasting waves

Radio waves A kind of electromagnetic light energy with wavelengths anywhere from a few centimeters to several kilometers long. Radio waves can be used to carry signals to and from spacecraft and Earth.

Radio wavelengths radio waves are the longest out of all the waves in the electromagnetic spectrum The shortest radio waves are about 100 yards.

Frequencies *Radio frequencies represent a subsection of electromagnetic energy found on the energy spectrum. *Signal strength differentiates the different types of radio waves, and all radio waves fall between 1 mm and 100 km in distance, and 3 KHz to 300 GHz in frequency.

How Radio and light waves relate Both radio and light waves travel at the same speed 260, 000 miles per second.

AM/FM radio AM- broadcasted with a single specific carrier frequency. *more range *1 MHz, 300 m wavelength FM - broadcasted with a specific amplitude. *better quality *100 MHz, 3 m wavelength
