Acoustic Interferometer

Type of activity: demo

Activity code: 00000

Description:

See description on the first year experiments website. Look for interference between 3kHz and 10kHz. Example: 3.18KHz Note: Wavetek generator doesn't provide enough power for the microphone to pickup a strong signal (still visible but weak, about 2mVpp). Use the old analog generators for this.
