Answer
assertion is false but reason is true.
Explanation
Assertion (A) is false. Sound waves require a medium to propagate, such as air, water, or solids, but they cannot travel through a vacuum. On the other hand, light waves can propagate through vacuum.
Reason (R) is true. Light is an electromagnetic wave which does not require material medium and sound is a mechanical wave which requires medium to travel.
