Question

Sound diffracts around obstacles more than light because:
  1. A
    Sound is slower
  2. B
    Sound wavelength (~cm to m) is comparable to everyday obstacles, light wavelength is not
    Correct
  3. C
    Sound has higher frequency
  4. D
    Diffraction is only for sound

Correct answer

Sound wavelength (~cm to m) is comparable to everyday obstacles, light wavelength is not

Explanation

Diffraction is significant when λ ≈ obstacle size. Sound: λ ∼ cm to m. Everyday objects (doors, buildings) are same scale. Light: λ ~ 500 nm — microscopic, so light doesn't bend around large everyday obstacles.
