The class is about heat, waves, and light. The website wants exactly the perfect answer and in the same metric system units that are stated on the calculators that are on the picture for the question, if not, it'll mark it wrong.

Set 12 Problem 1 Two loudspeakers are 4.74 m apart in a room at T = 20 .C. A person stands 3.13 m from one speaker and 3.56 m from the other. a. What is the lowest frequency at which destructive interference will occur at this point? (Assume the sounds are emitted in phase.) f1= Hz abc sin(x 1x10' 1029 Hz Submit Reset Reset All What is the condition for destructive interference, in terms of the distances from the sources to the receiver? b. Calculate the next two highest frequencies that also result in destructive interference at this point. 12 = HZ ab sin(x) Ox10' Submit Reset Reset Allf1= HZ abc sin(x 1x10 1029 HZ Submit Reset Reset All What is the condition for destructive interference, in terms of the distances from the sources to the receiver? b.
