A steel wire is used to stretch a spring. An oscillating
magnetic field drives the steel wire back and forth. A standing
wave with three antinodes is created when the spring is stretched
7.5 cm. What stretch of the spring produces a standing wave with
two antinodes?
Homework Answers
To have the same frequency go from being the 3rd harmonic to being the 2nd harmonic, the speed will have to increase by 3/2 of it's original speed
now Tension T is proportional to square of velocity
So the tension and therefore stretch will have to increase by the square of 3/2
so the stretch will increase by a factor of 9/4
so new strectch= 7.5*(9/4)=16.875 cm
