In physics lecture, we know that the formula for wave
speed on a harmonic series is given as:
v = sqrt ( T / (M/L))
Where,
v = wave velocity in m / s = unknown
T = tension force in Newtons= 338 N
M/L = mass per unit length in kg / m = 0.01 kg / 2 m =
0.005 kg / m
Therefore substituting the given values to the equation
will result in:
v = sqrt (338 N / (0.005 kg / m) )
v = sqrt (67,600 m^2 / s^2)
v = 260 m / s
