A string of length 4 m consits of twosections of equal length. The left has mass per unit length0.00022 kg/m, while the right has a mass per unit length 0.00066kg/m. Tension in the string is 790.5 N/m. Find thespeed at which transverse wave pulses travel in the leftsection. Find the speed at which transverse wave pulsestravel in the right section. Find the time required for apulse to travel from one end of the string to the other.
