Resonance-Tuning Forks

Driving Question:

Why does the first tuning fork resonate the second tuning fork without being struck?

This project will Basically display the principles of"Vibrations" ,"Acoustics" & "Frequencies."

Materials:

• Two Identical Tuning Forks and Wooden Sound Boxes

• Rubber Mallet

Procedures:

1. Strike First Tuning Fork to Demonstrate Vibrations and Frequency

2. Hold up sound box to microphone so that sound may be heard

3. Position sound boxes in front of each other with the "sound hole" facing each other

4. Strike first Tuning Fork

5. silence first Tuning Fork and pick up second sound box

6. Hold up sound box two to microphone

Principles:

After the first tuning fork is struck, one can hear sound. This is called a frequency. The Vibration felt through the sound box is present through the principles of acoustics where the sound bounces around in the wood box. Combining all of these principles, Resonance is created. The First tuning fork and the Second tuning forks and sound boxes are identical. Due to the fact that they have the same Frequency, the vibrations and frequency of the First Tuning Fork causes the second tuning fork to resonate.
