Answer: x=3.16m
Step-by-step explanation:
The condition for destructive interference is given by:
∆r = r1 - r2 = (m + 0.5)lamda
Where
Lamda = speed/frequency
= 343/260 = 1.32m
r1. = x
r2 = 2.50m
Then;
X - 2.5 = (m + 0.5)v/f
X - 2.5 = (m + 0.5)1.32
For m = 0 i.e at maximum destructive interference
x = 3.16m
