Which of the following statement is false?

Options

  1. ASound and light waves exhibit interference.
  2. BSound and light waves exhibit diffraction.
  3. CLight wave exhibits polarisation, while sound wave does not.
  4. DSound wave exhibits polarisation, while light wave does not.

Correct answer

D. Sound wave exhibits polarisation, while light wave does not.

Step-by-step solution

Polarisation is the property of wave to oscillates in more than one orientation. The sound waves always oscillates in the direction of wave propagation, so polarisation is not possible in them. While light can be polarised.
