Question

The propagation of wave from transmitter to receiver by touching ground in between them and goes through different layers is called _____

(a) Multi-hop single layer

(b) Single hop multi layer

(c) Multi hop multi layer

(d) Single hop single layer

I had been asked this question in semester exam.

My doubt is from Multi Hop Propagation topic in division Virtual Height, Critical Frequency and Muf of Antennas

Answer 1

The correct answer is (c) Multi hop multi layer

Best explanation: Multi hopping means the wave touches the ground once or more than once while travelling from transmitter to receiver. If it propagates through the multiple layers then it is called multi-hop multi layer.  In single hopping the wave doesn’t touches the ground.
