प्रश्न
Assertion: Energy could be transferred through matter by mechanical waves.
Reason: Light waves, heat waves and sound waves do not require a medium for their propagation as these are not mechanical waves.
पर्याय

उत्तर
If Assertion is true, but the Reason is false.
Explanation:
Assertion (A) is true. In wave motion, energy is transferred from one point to another without any net transfer of matter.
Reason (R) is false. A medium having elasticity and inertia is required only for mechanical waves, such as sound waves. Electromagnetic waves, such as light, can propagate through vacuum and do not require a material medium.
Therefore, A is true, but R is false.
