Q1. What is diffraction in the context of RF waves?
A. The bending of RF waves as they pass through a medium
B. The reflection of RF waves off a smooth surface
C. The redirection of RF waves around obstacles or through openings
D. The scattering of RF waves by irregular surfaces
Correct Answer: C - The redirection of RF waves around obstacles or through openings
Explanation:
Diffraction involves the bending or spreading of RF waves as they encounter obstacles or openings that are on the order of their wavelength. It allows RF signals to propagate around obstacles and through small openings.
