Homework Statement
A rope, under a tension of 209 N and fixed at both ends, oscillates in a second-harmonic standing wave pattern. The displacement of the rope is given by
y=0.49sin(πx/3)sin(12πt)
What are (a) the length of the rope, (b) the speed of the waves on the rope, and (c)the mass of the rope? (d) If the rope oscillates in a third-harmonic standing wave pattern, what will be the period of oscillation?
Homework Equations
T=2π/w
The Attempt at a Solution
I have solved part a,b,c but I got part d wrong. I simply used T=2π/w
==> T=2π/(12π)=0.1666666...=0.167s
And this is not the correct answer.
Please point out where I did wrong
