MCQ
Which of the following statement is false:
  • A
    Sound and light wave exhibit interference.
  • B
    Sound and light wave exhibit diffraction.
  • C
    Light wave exhibits polarization while sound wave does not.
  • ✓
    Sound wave exhibits polarization while light wave does not.
✓

Answer

Correct option: D.
Sound wave exhibits polarization while light wave does not.
Polarization is a property of waves that can oscillate with more than one orientation. Electromagnetic waves such as light exhibit polarization, as do some other types of wave, such as gravitational waves.
Sound waves in a gas or liquid do not exhibit polarization, since the oscillation is always in the direction the wave travels.
