Question 24

Sound

The physical properties of sound waves can best be described by

  1. A.reflection and diffraction
  2. B.polarization and reflection
  3. C.polarization and diffraction
  4. D.polarization and refraction
Show the answer and explanation

Answer: A (reflection and diffraction)

Explanation

Sound is a longitudinal wave, so it cannot be polarized. It does show reflection (echoes) and diffraction (bending round corners).
