The phenomenon of polarisation of light confirmed that light waves are
- A transverse in nature
- B longitudinal in nature
- C electromagnetic in nature
- D particles in nature
Answer & Solution
Correct Answer
(A) transverse in nature
Step-by-step Solution
Detailed explanation
Polarization involves the restriction of wave vibrations to a single plane, which is only possible if the vibrations are perpendicular to the direction of propagation. Since longitudinal waves (like sound) vibrate parallel to their direction of travel, they cannot be polarized,…
