A string consists of two parts attached at x=0 , The right part of the string `(xlt 0)` has mass per unit length `mu_r` and the left part of the string ` (xlt 0)` has mass per unit length ` mu _l` The tension in the string is T. If a wave of units amplitude travels along the left part of the string,what is the amplitude of the wave that is transmitted to the right part of the string?

A

` 1`

B

` (2)/( 1+sqrt (mu _l //mu _y))`

C

` (2)/( 1+sqrt (mu _l //mu _y))`

D

` (sqrt( mu_l //mu_y)-1)/( sqrt(mu_l //mu_y )+ 1)`
