Yan 20 poin The acoustical system shown in the figure is driven by a speaker emitting a monotonic sound of frequency 680 Hz, creating a sound wave of X=0.500 m inside the tube. Initially, the upper U-shaped tube has length of 1.12-m and the lower U- shaped tube has length of 1.37-m. Then the length of the upper U-shaped tube is varied by pulling the sliding section. Will the observer hear anything? Sliding section IN Speaker Receiver
When the length of the upper tube is 1.37 m. When the length of the upper tube is 1.87 m. When the length of the upper tube is 1.20 m. When the length of the upper tube is 1.62 m.. 1. Yes, he can hear the sound, it is the loudest. 2. Yes, he can hear some sound, but not very loud. 3. No, he cannot hear any sound.
