The vertical position y of a single point on the string is measured at fixed intervals of time t as the wave passes. The graph above shows y as a function of t for the point. A separate measurement indicates that the wave speed on the string is 12 m/s. The wavelength of the wave is most nearly 0.0021 m (A) (В) (C) (D) 480 m 0.15 m 0.30 m

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.
