Question

Tanner is running his finger around the top of a crystal glass with a natural frequency of 1100 hertz. If Tanner can cause the glass to resonate, it could create a high-pitched sound and shatter.

What does he need to do to create that resonance?

A). vibrate the glass at 550 hertz

B). vibrate the glass at 1100 hertz

C). increase the loudness of the vibration

D). decrease the loudness of the vibration

Answer 1

B, vibrate the glass at 1100 hertz.

Step-by-step explanation:

on edge

Answer 2

The correct answer option is B) vibrate the glass at 1100 hertz.

Step-by-step explanation:

We know that Tanner is running his finger around the top of a crystal glass with a natural frequency of 1100 hertz.

So to cause the glass to resonate and produce high-pitched sound, he needs to vibrate the glass at 1100 hertz.

Resonance is a phenomenon which results when the frequency at which a force is periodically applied is equal (or nearly equal) to one of the natural frequencies of the system on which it acts.

Therefore, causing the system to resonate.
