Q.Which of the following phenomenon does not occur to both sound and light waves?

Polarisation is possible only for transverse waves; since sound is longitudinal, it cannot be polarised, unlike light.

Interference, diffraction, and coherence effects can occur for both longitudinal (sound) and transverse (light) waves, since they depend only on the general wave nature (superposition) of the disturbance. Polarisation, however, is the restriction of vibrations to a single plane — this concept applies only to T …
