Two Loudspeakers Are Placed A Distance Of 6 M Above And Below One Another And Driven By The Same Source At A Frequency O 2 (63.86 KiB) Viewed 46 times
Two loudspeakers are placed a distance of 6 m above and below one another and driven by the same source at a frequency of 641.74 Hz. A detector is positioned a perpendicular dis- tance of 13 m from the two speakers and a vertical height 4.2 m from the lower speaker. This results in constructive interference at the first order maximum.
13 m - center line- intensity 4.2 m 1. Unable to determine 2. Constructive 3. Destructive 6 m- What minimum distance directly toward or away from the detector should the top speaker be moved in order to create destructive inter- ference between the two speakers at the loca- tion of the detector? The velocity of sound is 345 m/s. Answer in units of m. 014 (part 2 of 2) 10.0 points If the top speaker is moved by twice the dis- tance calculated in the previous part, what will the interference be?
