What is the effect of scattering on a radio wave?
- A A portion of the wave abruptly changes direction
- B The wave is absorbed by the medium
- C The wave gets redirected in many directions
- D The wave is gradually bent
Correct answer: C — The wave gets redirected in many directions. From the official ISED question bank, verified word for word.
Why
Scattering happens when a radio wave hits rough surfaces or small objects, causing the energy to bounce off in many different paths rather than continuing straight. The full explanation — and one for every question — is in Pro.
