In figure a, string 1 has a linear mass density of 3 g/m, and string 2 has a linear mass density of 4.5 g/m. They are under tension due to the hanging block of mass M = 500 g as shown in figure (a)

The block is now divided into two blocks (with M1 + M2 = M) and the apparatus is rearranged as shown in figure b. If the speeds of transverse waves in the two strings are equal the values of M1 and M2 will be respectively

A string consists of two parts attached at x = 0. The right part of the string (x > 0) has mass mr per unit length and the left part of the string (x < 0) has mass mr per unit length. The string tension is T. If a wave of unit amplitude travels along the left part of the string, as shown in the figure, what is the amplitude of the wave that is transmitted to the right part of the string?
