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 |r2|-|r1| = 0.8 m. Rank the following situations according to the intensity of sound at the receiver from the highest to the lowest. Assume the tube walls absorb no sound energy. Give equal ranks to situations in which the intensity is equal.
(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.
