Which factors determine the frequency of a tuning fork ?

Explanation

(i) Length of the prongs(l). The pitch (v) is inversely proportional to the square of the length (l) of the prongs. i.e., `vprop1//l^(2)`.
(ii) Thickness of the prongs (b). The pitch (v) is directly proportional to the thickness (b) of the prongs, i.e., `vpropb`.
(iii) Elasticity of the material (Y). The pitch is directly proportional to the square root of the young's modulus of elasticity (Y) of the material, i.e., `vpropsqrt(Y)`.
(iv) Density of the material `(rho)`. The pitch (v) is inversely proportional to the square root of the density of the material, i.e., `vprop(1)/(sqrt(rho))`.
