1. radio waves. 1) frequency range is in the range of 107-109 Hz. Radio wave frequency from 2) 530 – 1600 kHz radio station will send a broadcast system, A.M. 3) frequency range at lower range 530 – 1600 kHz long wave frequency is called the higher is also called short waves. 4) frequency range from 88 – 108 MHz, is sending wave F.M. 5. radio waves that send out signals) from the station and sent to the receiver, there are two types of. 5.1 means radio waves ground waves that are transmitted from the station sent radio receiver directly with the whole system. A. M. and F.M. 5.2 the waves blue means the radio waves that send up to reflect the atmosphere ionosphere and come back later to get the radio (F.M. system there is no A.M. system, because the wave passes through the atmosphere, this class F.M.)
