Another formula for the speed of a wave on a string is given by V=Tμ, where T and μ are Tension and mass per unit length respectively. Consider and electric guitar having six strings. If one of the strings is plucked, transverse waves travel on the string. The length of high pitch string between two fixed points is 62.0 cm and the mass is 280 g. If the string is under a tension on 457 N, find the speed of the wave on the high pitch string. No need to include units with your final result. HINT: since the tension is in N, make sure all the other measurements are in the S.I. units.
Determine d such that ∂2B/∂z2 = 0 at z = 0 on the z-axis and show that for this configuration, the third derivative of the field with respect to z is also zero at z = 0.
