Question

4. Why does a glass shatter when a loud high pitched sound affects it?​

Answer 1

Volume is a key player in the glass shattering game, because the loudness of a sound is directly related to the extent it displaces air molecules. In essence, the sound passes from molecule to molecule until it hits the glass. As Brunhilde sings louder, she is, in effect, pushing air at the glass harder.

Answer 2

Explanation:

This common phenomenon is known as resonance and occurs because the singer's voice displaces nearby air particles, which crash into the glass like invisible waves. And when the singer's voice is amplified, these waves get more powerful. With enough amplification, the glass can vibrate so strongly that it shatters.
