Question

Two speakers are acing each other and seperated by a d=2m. Both speakers are producing the same monotone sound with a wavelength of 1.4m. On the line between the speakers how many points could an observer hear totally constructive interference? 1 2 3 4 5 Measures from one of the speakers, where are the points of total destructive interference located? .15,1.55 .3,1.00 .45,1.95 .65,1.35 .90,1.60 Two speakers are acing each other and seperated by a d=2m.

Explanation / Answer

the condition for the constructive interference is,

d = m*wavelength

the number of points observed is,

m = d/wavelength

= 2 / 1.4

= 1.4

= 1
