Wave Nature and Polarization

Assertion (A): Wave nature can be proved by phenomena of interference and diffraction.
Reason (R): Only transverse wave can show the phenomena of polarization.
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Solution:

Assertion (A) is true. Interference and diffraction are characteristic wave phenomena, providing strong evidence for the wave nature of light.

Reason (R) is true. Polarization is a property exclusive to transverse waves, where oscillations are perpendicular to the propagation direction.
Reason (R) describes a unique property of transverse waves, which is distinct from demonstrating wave nature via interference/diffraction. Thus, (R) does not explain (A).
