Path difference for constructive interference,
Path difference for destractive interference,
Separation of points A and B, L = 5.00 m
Let A be at x = 0 and B be at x = 5.00 m.
Sum of the radial distance, rA + rB = 5.00 m
rB = 5.00 - rA
Path difference, |Δx| = rA - rB = ( rA - (5.00 - rA ) = 2rA - 5.00
The displacement |Δx| can be positive or negative based on the reference point.
mode, m = 0
Two coherent sources of radio waves, A and B, are 5.00 meters apart. Each source emits waves with wavelength of 6.00 meters. Consider points along the line connecting the two sources.
a) At what distance from source A is there constructive interference between points A and B?
b) At what distances from source A is there destructive interference between points A and B?
