Hey just finished this question on mastering physics.
The velocity of a wave is defined as wavelength*frequency.
it is also defined as sqrt(Tension/(mass/rope length)).
Set the two definitions equal to each other and solve for the Tension and you should have your answer!
With what tension must a rope with length 2.10m and mass 0.115kg be stretched for transverse waves of frequency 39.0hz to have a wavelength of 0.790m ?
