What is the range of frequencies used in satellite communication? What is common between these waves and light waves?          

Answer:

                The following two frequency bands are used for satellite communication: \[\text{5}.\text{9 }-\text{ 6}.\text{4 Hz}\] for uplink \[\text{3}.\text{7 }-\text{ 4}.\text{2 GHz}\] for downlink. The waves used for satellite communication and light waves are both electromagnetic waves which travel through free space with a speed of\[3\times {{10}^{8}}m{{s}^{-1}}\].
