Three pieces of a string, each with length ?, are joined together end to end, to make a combined string of length 3?. The first piece of string has mass per unit length ?1, the second piece has mass per unit length ?2 = 4?1, and the third piece has mass per unit length ?3 = ?1/4. a. If the combined string is under tension ?, how much time does it take a transverse wave to travel the entire length 3?? Give your answer in terms of ?, ?, and ?1. b. Does your answer to part (a) depend on the order in which the three pieces are joined together? Explain.

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.
