Question: the frequency of low-frequency tuning forks is determined by?
Answer: Calculation of frequency f is the frequency the fork vibrates at in hertz. 1.875 is the smallest positive solution of cos(x)cosh(x) = −1. l is the length of the prongs in metres. E is the Young's modulus (elastic modulus or stiffness) of the material the fork is made from in pascals.
