Question

Which of the following statements is false regarding the spatial distribution of a wavefront?

(a) Multipath components are collinear with direct path

(b) Multipath components have less signal strength than direct path

(c) Multipath components are present

(d) Multipath components exhibit time delay

I got this question in an international level competition.

Answer 1

The correct answer is (a) Multipath components are collinear with direct path

For explanation: Multipath components exhibit delay with respect to main components. They are not collinear with direct path. They have less signal strength than direct path. When interference is present, it tends to mix with multipath components.
