(a) An obstacle blocking the line of sight produces a diffraction loss of 18dBs between transmitter and receiver of height 15 meter each. If the separation between transmitter and receiver is 5 km and the obstacle lie exactly in the middle, find the total height of obstacle and the number of fresenel zones which are being blocked by this obstacle. Assume a frequency of 200MHZ.
