Which of the following phenomenon is NOT common to sound and light waves?

Question

G1 Physics · Accepted Answer

Step 1: Both sound and light exhibit interference and diffraction, and can be coherent. Step 2: Ordinary sound in air is a longitudinal pressure wave, so it cannot be plane polarised like a transverse electromagnetic wave. Step 3: Light can be polarised because electric and magnetic fields oscillate transversely. Final answer: (D) Polarisation.
