Let's say that there are 2 speakers, A and B. They are equidistant from location Q and differ in distance from Location P. Speaker A is closer to Location P than Speaker B is to Location P. Both speakers emit sound waves and are in phase with each other.
The problem asks me to find the relationship between the amplitude of the resultant wave at both Locations.
The Attempt at a Solution
I understand that since they are equidistant from Location Q, they are in sync and will interfere constructively. But since they differ in distance from Location P, the waves will not be in sync. Since they are not in sync, does this mean that the waves will interfere destructively? The resultant wave can also interfere constructively, but the amplitude will not be as great as the amplitude of the resultant wave at Location Q.
So either way, AQ > AP
Is this reasoning correct?
