Answer 1

When a tuning fork vibrates over an open pipe and causes the air in the pipe to vibrate, the vibrations in the tube are caused by **C) resonance**.

Resonance occurs when the frequency of the tuning fork matches the natural frequency of the air column in the pipe, leading to an amplification of the vibrations.
