1. The problem statement, all variables and given/known data A 285Hz sound wave is directed into one end of a trombone slide A microphone is placed at the other end to record the intensity of sound waves that are transmitted through the tube. The straight sides of the slide are 80cm in length and 10cm apart with a semicircular bend at the end For what slide extensions will the microphone detect a maximum of sound intensity? express your answer using two significant figures. If there is more than one answer, enter your answers in ascending order separated by commas. 2. Relevant equations maybe the equations for an open closed tube i think. wavelength at specific mode= 4L/m m=mode L= length also V=frequency x wavelength 3. The attempt at a solution L= 0.8m +0.05pi+ 0.8m (The 0.05pi is half the circumference to find the length of the semicircle) Please i really want to understand this question but dont no where to go? Is a trombone an open closed tube?
