The acoustical system shown in the figure below is driven by a speaker emitting sound of frequency 781 Hz. (Use v 343 m/s.) Sliding section Receiver Speaker (a) If constructive interference occurs at a particular instant, by what minimum amount should the path length in the upper U-shaped tube be increased so that destructive interference occurs instead? m (b) What minimum increase in the original length of the upper tube will again result in constructive interference? m
The acoustical system shown in the figure below is driven by a speaker emitting sound of frequency 716 Hz. (Use v = 343 m/s.) A rectangular tube where the top section is comprised of a sliding U-shaped part has an opening at the center of the left and right sides of the tube. A speaker is pointed at the opening on the left side and shows sound waves entering the tube going through both paths towards the right opening. A...
