In Figure (a), string 1 has a linear density of 2.14 g/m, and string 2 has a linear density of 7.16 g/m. They are under tension due to the hanging block of mass M = 490 g. Calculate the wave speed on (a) string 1 and (b) string 2. (Hint: When a string loops halfway around a pulley, it pulls on the pulley with a net force that is twice the tension in the string.) Next the block is divided into two blocks (with M1 + M2 = M) and the apparatus is rearranged as shown in Figure (b). Find (c)  M1 and (d)  M2 such that the wave speeds

Stretched string

A stretched string is a wire which is made up of any metal that must have a larger length compared to its thickness. The ends of the wire are fixed, and when they oscillate or are plucked, it produces two reflected transverse waves of the same frequency and same amplitude. The waves or pulses are traveling in alternate directions and superimpose with one another. This waveform is named standing or stationary waves.
