b)A vibrating tuning fork is held next to an adjustable open-closed tube. Thefrequency of the tuning fork is also the fundamental frequency of the tube at its shortestlength. When the tube slowly increases its length, the fourth resonance is heard when thelength is 76.1 cm.Draw the standing wave pattern for the fourth resonance (indicate what type ofwave you use for the sketch).What is the frequency of the tuning fork? The air is 82.0 F. [Answer in 3ii.significant figures]

A "C" flute creates the note C4 when it is played at its resonance frequency, that is 261 Hz on the evenly tempered scale. Flute frequencies are changed by opening holes in its tube, creating a node at that hole and effectively shortening the 66 cm tube. The flute and the guitar make a good instrumental combination, and for that they must be tuned together. You have seen that a guitar's 6 strings are usually tuned to (E) 329.63 Hz E4 (B) 246.94 Hz B3 (G) 196.00 Hz G3 (D) 146.83 Hz D3 (A) 110.00 Hz A2 (E) 82.41 Hz E2 1. Is there a way to alter the frequency of the flute so that it matches one of these open strings at resonance? Explain your answer. 2.
