A lecturer is demonstrating two-slit interference with sound waves.Two speakers are used, 1.3 m apart. The sound frequency is 1200 Hzand the speed of sound is 343 m/s. Students sit facing the speakersin a row of seats 6.2 m away.
Along the row of students, what is the spacing between thelocations on either side of the center line between the speakerswhere no sound is heard because of destructive interference?
Answer in units of m.
*I have a decent picture drawn, frequency converted to wavelength,etc.
Cannot figure out what distance it is that I'm solving for....Thanks anyone.
