Diffraction MCQs

Practice Diffraction MCQs with four options, answers and explanations for focused Electronics & Telecommunication Engineering revision.

Question 1
Antenna & Wave PropagationDiffraction

Diffraction is especially important in radio propagation when a wave encounters?

  • AAn obstacle or sharp edge near the propagation path
  • BA perfectly matched load only
  • CA DC power source
  • DAn ideal isotropic point with no obstacle
Report an error
Correct Answer: A. An obstacle or sharp edge near the propagation path
Explanation: Diffraction bends/spreads waves around edges and obstacles, enabling some reception even when direct line of sight is obstructed.
Reference: Standard antenna and wave propagation: diffraction
