Tuning Fork Set of 8 – Welch Type
Product Code : SCL-ES-11438
Description:
The Educational Instruments Tuning Fork Set of 8 (Welch Type) is a fundamental and indispensable piece of Physics Science educational laboratory equipment for teaching acoustics and wave properties. This set provides eight individual, high-quality steel instruments, each precisely calibrated to generate a constant and specific pitch or frequency when struck.
The typical set includes standard frequencies such as 256 Hertz (C), 288 Hertz (D), 320 Hertz (E), 341.1 Hertz (F), 384 Hertz (G), 426.6 Hertz (A), 480 Hertz (B), and 512 Hertz (C). The U-shaped design ensures the generation of a pure tone with minimal overtones, making it an ideal source for accurate and reliable sound production in experiments illustrating sound waves, resonance, and vibration.
Usage:
The Tuning Fork Set is essential for conducting core experiments in wave physics, helping students understand the quantitative nature of sound.
Frequency and Pitch Relationship: The primary use is to strike different forks to directly demonstrate that pitch is determined by the frequency of the sound wave.3 The graduated set allows for comparative study of musical intervals and scales.
Sound Wave Generation: Striking a fork generates a clear sound wave composed of areas of high pressure (compressions) and low pressure (rarefactions) in the air.4 This visually demonstrates the longitudinal nature of sound.
Resonance and Harmonics: The forks can be used with a resonance tube or sonometer to find the speed of sound in air or to demonstrate the phenomenon of resonance, where maximum vibration occurs when the driving frequency matches the natural frequency.5
Beats: By striking two forks with very close, but slightly different, frequencies (e.g., 256 Hertz and 288 Hertz), students can clearly hear the oscillating loud and soft pattern known as beats, demonstrating the superposition principle of waves.
Music Education: Used to establish precise reference pitches for musical training, choir practice, and understanding the scientific basis of musical temperaments.
Educational Applications & Learning Goals:
This set supports foundational instruction in Physics, Music Theory, and Auditory Science:
Wave Properties: Understanding key concepts like frequency, wavelength, amplitude, and speed of sound.
Resonance Principle: Gaining practical experience with the principle of resonance, which is vital in fields from music to engineering.7
Acoustics Fundamentals: Providing a high-quality, constant sound source for quantitative laboratory measurements related to sound.
Interdisciplinary Learning: Connecting the physics of vibration and waves directly to the concepts of musical pitch and harmony.
