In the figure below, a sound wave of wavelength 0.8 m divides into two equal parts that recombine to interfere constructively,with the original difference between their path lengths being |r, - r,| = 0.8 m. Rank the following situations according to theintensity of sound at the receiver from the highest to the lowest. Assume the tube walls absorb no sound energy. Give equal ranksto situations in which the intensity is equal. (Use only the symbols > or =, for example a > b = c).(a) From its original position, the sliding section is moved out by 0.1 m.(b) Next it slides out an additional 0.1 m.(c) It slides out still another 0.1 m.(d) It slides out 0.1 m more.Sliding sectionReceiverSpeaker

Sound (speed = 343 m/s) exits a diffraction horn loudspeaker through a rectangular opening like a small doorway. A person is sitting at an angle a off to the side of a diffraction horn that has a width D of 0.068 m. This individual does not hear a sound wave that has a frequency of 8400 Hz. When she is sitting at an angle of a/2, the frequency that she does not hear is different. What is this frequency? Number i Units
A sound wave enters the thin tube at P and exits at Q. Assume r = 0.41m and the wavelength is 1.86m. What is the smallest length d that results in destructive interference at Q?
Two loudspeakers, 1.7 m apart, emit sound waves with the same frequency along the positive x-axis. Victor, standing on the axis to the right of the speakers, hears no sound. As the frequency is slowly tripled, Victor hears the sound go through the sequence loud-soft-loud-soft-loud before becoming quiet again. What was the original sound frequency? Assume room temperature of 20∘C.
