In order for sound to be "heard" it must first vibrate the small bones in the inner ear against the oval window.  This converts sound waves from the air into fluid waves which propagate the movement of fluid through the bony structure called the ___________________.   The wave pushes on the basilar membrane where it deflects the __________________ that extend from both inner and outer hair cells.  This deflection tugs on tip links which are connected to _____________________ channels which convert the fluid wave

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.
