Acoustic resonance apparatus
Product Code : SCL-ES-12778
The Acoustic Resonance Apparatus by Educational Instrument India is a high-quality physics laboratory instrument designed for studying sound waves, resonance, frequency, wavelength, standing waves, and the velocity of sound in air. It is commonly used in school physics laboratories, college laboratories, STEM classrooms, and technical institutes for practical demonstrations in acoustics and wave motion.
This apparatus helps students understand how resonance occurs when the natural frequency of an air column matches the frequency of a vibrating source such as a tuning fork. By adjusting the length of the air column, students can observe resonance points and use them to calculate the wavelength and speed of sound.
The Acoustic Resonance Apparatus is a valuable teaching aid for demonstrating the relationship between sound, vibration, air columns, frequency, and resonance. It provides a practical and visual method for learning important sound wave concepts through hands-on experimentation.

How to Use Acoustic Resonance Apparatus
Place the Acoustic Resonance Apparatus on a stable laboratory table.
Fill the water reservoir or tube system as per the experiment requirement.
Select a tuning fork of known frequency.
Strike the tuning fork gently with a rubber hammer to produce sound vibration.
Hold the vibrating tuning fork near the open end of the resonance tube.
Adjust the water level or air column length slowly.
Listen carefully for the loudest sound, which indicates resonance.
Record the length of the air column at the resonance position.
Repeat the process for another resonance point if required.
Use the recorded readings to calculate wavelength and velocity of sound in air.
After the experiment, drain water if necessary and clean the apparatus properly.
