Question

will the sound produced by your guitar be the same if the cavity of the box is filled with sand? Give reasons for your answer​

Answer 1

Answer:

The guitar string forces the sound box to begin vibrating at the same frequency as the string. The sound box in turn forces surrounding air molecules into vibrational motion. Because of the large surface area of the sound box, more air molecules are set into vibrational motion. This produces a more audible sound.
