Stationary wave apparatus
Product Code : SCL-ES-12771
The Stationary Wave Apparatus by Educational Instrument India is a practical physics laboratory instrument designed to demonstrate stationary waves, also known as standing waves, in a stretched string or wire. It is widely used in school physics laboratories, college labs, STEM classrooms, and technical institutes for teaching wave motion, vibration, frequency, wavelength, tension, resonance, nodes, and antinodes.
This apparatus allows students to observe how stationary waves are formed when two waves of the same frequency and amplitude travel in opposite directions and interfere with each other. By adjusting the tension, length, or frequency of vibration, learners can clearly see different wave patterns and understand the relationship between wave speed, frequency, and wavelength.
Built for educational use, the Stationary Wave Apparatus provides a simple and visual method for explaining important wave concepts. It is suitable for classroom demonstrations, practical experiments, and hands-on physics learning.

How to Use Stationary Wave Apparatus
Place the apparatus on a stable laboratory table or demonstration bench.
Attach one end of the string to the vibrator or vibration source.
Pass the other end of the string over a pulley and attach suitable weights to create tension.
Connect the vibrator to the recommended power supply.
Switch on the power supply and allow the string to vibrate.
Adjust the tension, frequency, or length of the string until a clear stationary wave pattern is formed.
Observe the nodes, where the string appears still, and antinodes, where maximum vibration occurs.
Measure the distance between nodes to calculate wavelength.
Record readings and use them to study the relationship between frequency, wavelength, tension, and wave speed.
After the experiment, switch off the power supply and remove the weights safely.
Educational Importance
The Stationary Wave Apparatus is an important teaching aid for understanding wave interference and resonance. It helps students visually observe how standing waves form and how wave patterns change with tension and frequency. This makes it easier to explain theoretical concepts such as nodes, antinodes, wavelength, natural frequency, resonance, and wave speed.
By using this apparatus, students gain practical experience in observation, measurement, calculation, and scientific analysis. It supports hands-on learning and improves understanding of wave behaviour in physics.
