Question

With what tension must a rope with length 5. 0m and mass 0. 16kg be stretched for transverse waves of frequency 60. 0Hz to have a wavelengths of 0. 80m?

Answer 1

We know that

$n=\frac{1}{2l}\sqrt{\frac{T}{m}}$

Put value

$60=\frac{1}{2\times5}\sqrt{\frac{T}{0.16}}$

$600=\sqrt{\frac{T}{0.16}}$

T=576N
