Vedclass · Answer

(D) Television signals are transmitted as space waves (line-of-sight propagation). Because the earth is curved,the signal cannot follow the curvature of the earth beyond the horizon. The transmission is limited by the line-of-sight distance between the transmitting antenna and the receiving antenna. Therefore,the curvature of the earth prevents the reception of signals at large distances.

Television signals on earth cannot be received at distances greater than $100\, km$ from the transmission station. The reason behind this is that
