Question 1 Report

Under constant tension and constant mass per unit length, the note produced by a plucked string is 500Hz when the length of the string is 0.90m. At what length is the frequency 150Hz?

Answer Details

F = $\frac{1}{2 L}$ $\sqrt{\frac{T}{m}}$

F1L1 = F2L2

500 x 0.9 = 150 x L2

therefore, L2 = 3m
