A string of length L consists of two distinct sections. The left half has linear mass density mu_(1) = mu_(0)//2 , while the right half has linear mass densitymu_(2) = 3 mu_(0) Tension in the string is F_(0). The time required for a transverse wave pulse to travel from one end of the string to the other is:

Answer»

`L/4 SQRT(mu_(0)/F_(0)) (sqrt(2) + sqrt(6))`
`L/2 sqrt((2mu_(0))/f_(0)) (1+ sqrt(3))`
`L/2 sqrt((mu_(0))/(2F_(0))) (sqrt(2) + sqrt(6))`
`L/2 sqrt((mu_(0))/(2F_(0)) (1 + sqrt(6)))`
