Why it's a great deal

• * Tuning fork is the basic instrument of acoustics. It demonstrates the occurrence of sound, the interference of sound can measure the speed of sound and verify the conduction of sound waves, and can do various other acoustic experiments.

• * The tuning fork is forged from high-quality 45# round steel, and the is chrome-plated; the resonance box is made of pine.

• * In a static and silent room, insert two tuning forks on the resonance box respectively, make them about half a meter apart from each other, and make the openings of the two resonance boxes face each other, and then excite one of them. After 2 to 3 seconds, use The sound of the second tuning fork can be heard when the hand touches it. If you put a frequency conversion hoop on the fork strand of one of the tuning forks, and then excite the other, the frequencies of the two tuning forks are no

• * The tuning fork must be prevented from being dropped and subject to high heat to prevent frequency changes. The excitation fork must be knocked with a soft hammer. After use, the is coated with a non-acid anti-rust oil.

• * The tuning fork and the resonance box should have a reliable connection. Inserting and removing the tuning fork should avoid shaking to prevent the jack from becoming a horn shape and causing looseness, which will affect the
