NEET Physics Question - Waves - Sound Wave and its Characteristics

Assertion (A): A vibrating tuning fork sounds louder, when its stem is pressed against a desk top.

Reason (R): When a sound wave is incident on the surface of a desk, it is totally reflected.

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

Assertion (A) is true due to forced vibrations and resonance. The desk provides a larger surface area to vibrate, increasing the loudness.

Reason (R) is false because sound waves are not totally reflected; some energy is transmitted to the desk.
