(adsbygoogle = window.adsbygoogle || []).push({}); A harpsichord string of length 1.60 m and linear mass density 25.0 mg/m vibrates at a (fundamental) frequency of 450 Hz.

(a) What is the speed of the transverse string waves?

I did 450 x 2(1.60) = 1440 m/s which is correct.

(b) It asks for the tension.

I tried it but am not getting the right answer.

I used

v = square root of (F / (m/L)) where v = 450 Hz, and m/L is 25000 kg/m

So 1440 = squre root of (F/25000)

F = 82.8 N which is incorrect.

Not sure what I am doing wrong.

Thanks
