4) A guitar string, length L=6479 m, has mass 2.275 grams and when in tune, has tension Fr = 71.11 N. a) With mass in kg, find the linear mass density of the string, then the speed of the waves on the string. P kg/m b) When oscillating in its fundamental mode (n = 1) what are A, and f₁? Lopen = m Lclosed = This frequency causes an open tube to resonate, in air, in its second harmonic. c) What is the length of this open tube? m m/s f₁ == m Hz. This frequency causes an closed tube to resonate, in air, in its third harmonic. d) What is the length of this closed tube?

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.
