Two loudspeakers 6.0 m apart are playing the same frequency. If youstand 12.0 m in front of the plane of the speakers, centeredbetween them, you hear a sound of maximum intensity. As you walkparallel to the plane of the speakers, staying 12.0 m in front ofthem, you first hear a minimum of sound intensity when you aredirectly in front of one of the speakers.
Part A)
What is the frequency of the sound? Assume a sound speed of 340m/s.
I got 120.02 Hz. This is right, I checked.
Part B)
If you stay 12.0 m directly in front of one of the speakers, forwhat other frequencies between 100 Hz and 700 Hz is there a minimumsound intensity at this point?
Express your answer numerically. If there is more than one answer,enter your answers in ascending order separated by commas.
Sorry, I can't figure out this part B! Thanks so much.
