Why space wave propagation is limited upto small distance over earth's surface?

Text Solution

Verified by Experts

(i) Because the transmission of signal directly from the transmitting antenna to receiving antenna called line of sight communication.
(ii) The waves travelling directly from the transmitting antenna to the receiving antenna get blocked due to curvature of the earth.
(iii) It limits both the mnximum line of sight distance between the two antennas and also the maximum distance upto which transmission can be received.

Earthquakes generate sound waves inside the earth. Unlike a gas, the earth can experience both transverse (S) and longitudinal (P) sound wave. Typical the speed of S wave is about 4.0 kms^(-1) , and that of P wave is 8.0km s^(-1) . A seismograph records P and S waves from an earthquake. The first P wave arrives 4min before the first S wave. Assuming the waves travel in straight line, at what distance does the earthquake occur?
