Radio waves travel through space at a speed of light which is 186000 miles per second 300000000 meters per second. The speed of light is a little less than 300000 km per second. At that speed a beam of light could go around the Earth at the equator more then 7 times in a second.
What is the waves speed.
Actually radio waves travel very quickly through space. Speed of a wave wavelength X frequency. At 300 GHz the corresponding wavelength is 1 mm shorter than a grain of rice. More like this it should really read like below but couldnt get the formula right to put the equation in prop.
