Question 1 of 12 ncorrect ncorrect Map A sapling learn You are walking around a large open field. The only objects nearby are two identical speakers set some distance apart, which are both producing sound, in unison, with a wavelength of 4 m. As you wander around the field, you notice that at certain locations, the sound you hear is surprisingly loud, while at others it seems unusually quiet. You conclude that you are observing the effects of interference between the two sources of sound waves. For each of the locations given below, indicate what sort of interference would occur at that point. X Constructive interference Destructive interference In between 16 m from one speaker and 24 m from the other 11 m from one speaker 11 m from one speaker and 14 m from the other and 7 m from the other 8 m from each speaker 10 m from one speaker 19 m from one speaker and 8 m from the other and 14 m from the other 13 m from one speaker and 19 m from the other Incorrect. The sound waves will interfere constructively if they have the same phase when they arrive at the given point. The relative phase of the two waves is determined by the relative distance from each speaker to the point. Since the waves from each speaker start out in phase, they will still be in phase when they arrive at a point that is 8 m from each speaker. There will, therefore, be constructive interference at that point. A Previous Give Up & View Solution Try Again Next DI Exit

Explanation / Answer

Constrictive inetreference (path diffrence = n*lamda, n = 0,1,2,3,...)

1) 16m from one speaker and 24m from other speaker

2) 11m from one speaker and 7m from other speaker

3) 8m from each speaker

destructive intereference (path diffrence = (n+1)*lamda/2, n = 0,1,2,3,...)

1) 10m from one speaker and 8m from other speaker

2) 13m from one speaker and 19m from other speaker

in between

1) 11m from one speaker and 14m from other speaker

2) 19m from one speaker and 14m from other speaker
