How far should a cellist move her finger to adjust a string's tone from an out-of-tune 449.9 Hz to an in-tune 440.0 Hz? The string is 68.2 cm long, and the finger is 17.3 cm from the tuning nut for the 449.9-Hz tone. (Assume the tone comes from the portion of the string between the cellist's finger and the end opposite the nut.

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.
