Pair of Steel Tuning Forks (440Hz) in Wood Bases, One Adjustable: This set includes two tuning forks with bases and one mallet for demonstrating the production of beat frequencies. The pair comprises two nickel-plated forks, A (440 Hz ±5%), mounted on individual boxes. One fork is designed with adjustable mass, allowing its frequency to be shifted from the nominal 440 Hz. When both forks are sounded, a clearly audible "beat" is produced, its rate depending on the difference in frequency between the forks. Note: These tuning forks are designed for physics experiments and may not produce exactly 440Hz (typically 436-444Hz); however, they can be adjusted to create beats within each other or to match each other.
