A fibre is fixed at one end it is stretched over a pulley (2.0kg) is the mass. if the mass per unit length of the fibre is 82g/m, calculate the velocity of the wave on the stretched fibre. (please show working)
tension = T = m g = 9.8* 2
your book has the speed of a transverse wave in a string with tension T and mass per unit length mu
v = sqrt(F/mu) = sqrt (9.8*2/82)
