Most waves used for communication purposes rely on geostationary satellites because _____ Correct Answer they cannot transmit data at long distances due to curvature of the earth

Most communication waves cannot transmit data accurately over long distances due to the curvature of the earth. They can only do so in the line of sight. However, they are not reflected by the ionosphere like radio waves and can be relayed to a wide area using geostationary satellites.
