(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

string is under tension 400N. A 1m string has mass 5grams. what is the speed if the wavelength is 1m. What is the speed if the wavelength is .5m. What is the frequency?

2. Relevant equations

v = sqrt(Tension/(m/L))

v = f * wavelength

3. The attempt at a solution

a) v = sqrt(400N / (.005kg/1m) = 283m/s

b) im confused. whether to use the first or second equation?

v=sqrt(400N/.005kg/.5m) = 200m/s

c) f = v/wl = 200m/.5ms = 400Hz

is this correct?
