Apoint mass m is connected to a point on a string of mass per unit length p. a transverse wave aelatok) propagates with the velocity v in the positive x-direction along the string and is partially reflected and transmitted at the mass. the boundary conditions are as follows. the transverse displacements of the string just to the left and to the right of m are equal and the difference between the transverse forces just to the left and to the right of m equal the multiplication of m and its acceleration. show that the ratio of reflection coefficient and the transmission coefficient is = ( pon
