A string of length 8 m fixed at both the ends has a tension of 49 N and a mass 0.04 kg.
Find the speed of transverse waves on this string.

• SCIENCE -

You should have been taught about this formula for the wave speed, V.

V = sqrt (T/d)

T = tension = 49 N
d = density per length = 0.04/8 = 0.005 kg/m

V = sqrt(49/.005) = 99 m/s
