Beats in Sound Waves

Demonstrating Beat Frequency - A Video Project by Bo

Sound beats explained

Beats Physics

<p>A string emits an unknown sound. You strike a tuning fork which emits a sound at EXACTLY 300 Hz, and you hear a beat frequency of 20 Hz. You then tighten the string, increasing the tension in string. After you pluck the string and strike the tuning fork, you hear a new beat frequency of 30 Hz. What is the unknown frequency of the string, originally?</p>
