Question

AN instrument commonly used in laboratory to produce a sound of some particular frequency is?

Answer 1

Answer:

Tuning fork is your answer

Answer 2

Answer: A tuning fork is a tool used in laboratories to generate sound at a constant frequency.

Explanation:

• An acoustic resonator in the shape of a two-pronged fork with the prongs made from a U-shaped bar of elastic metal is known as a tuning fork.
• A tuning fork is an acoustic resonating instrument with two prongs that resemble U-shaped bars of elastic metallic material. It is employed to generate sound at a set frequency.
• For this reason, sound is generated in laboratory research using a tuning fork. The most popular tuning fork currently produces the note of A = 440 Hz, the common concert pitch used by many orchestras. The first string of the viola, the second string of the violin, and the cello's first string all have pitches of A.
• When struck on a surface or with an object to send it vibrating on it, it reverberates at a  fixed precise pitch and emits a clean musical tone once the high overtones have subsided or reduced. The length and mass of the two prongs determine the pitch that a specific tuning fork produces.
