A lecturer is explaining two-slit interference having sound waves. The two speakers are employed, 1.3 m apart. The sound frequency is around1200 Hz and the speed of sound is around 343 m/s. Students sit facing the speakers in a row of seats 6.2 m away.
All along the row of students, determine the spacing among the locations on either side of the center line among the speakers where no sound is heard because of the destructive interference?
