What material is the tuning fork made of and why?

Hint: The tuning fork is a two-pronged metal instrument that creates a fixed sound when hit and is used to tune musical instruments and determine the standard pitch.

Complete answer:
John Shore, a British musician, is often credited with inventing the tuning fork in the early eighteenth century.
A sound resonator with two prongs is known as a tuning fork. The tunes, or prongs, are made of a U-shaped metal bar (usually steel). This metal bar is free to move freely. As set vibrating by hitting it against an object, it resonates at a specific constant pitch.
A tuning fork is created from an alloy of steel, nickel, and chromium, known as Elinvar. A tuning fork is made from a material in which the elasticity of the material does not alter.
A tuning fork is a mechanism used in laboratory research to generate sound. The waves from the tuning forks are transferred to the surrounding medium as the prongs of the tuning fork touch the surface of the water.

Additional Information:Tuning fork therapy applies specific vibrations to various areas of the body using calibrated metal tuning forks. This will aid in the release of tension and energy and the promotion of emotional balance. It is used to function similarly to acupuncture, except instead of needles, it uses sound waves to stimulate points.

The length of its prongs determines the pitch generated by a tuning fork. Each fork is inscribed with the note it creates as well as its Hertz frequency. Prongs with shorter lengths make higher pitch (frequency) sounds than those with longer lengths.
