Wave length and frequency with Quincke tube

Equipment:
• quincke tube.
• Function generator.
• Speaker.
• oscilloscope.
• Metallic stand.
• Metallic base.
• Metallic multi clamp.

Description

• If a sound wave of a particular frequency is divided into two coherent components and if the path of one of the component waves is altered, it is  possible to calculate the wavelength of the sound wave and its frequency from the interference phenomena recorded with a microphone.
