Question

A wire of length 1.5 m is stretched by a force of 44 N. The diameter of the wire is 2 mm and its density is 1.4 g/cm³ . Calculate the frequency of the fundamental note emitted by it

Answer 1

With ususal notation, we are given that

L = 1.5 m, T = 44 N

D = 2 mm = 2 x 10^–3 m

ρ = 1.4 g/cm³ = 1400 kg/m³
