Question

what is relation between phase difference and path difference

Answer 1

$\huge \text{Phase\: Difference}$

➠ When a wave propagates through a medium the particles are different states vibration. Then, phase difference exits between two particles.

➠ Phase difference is the difference of angle between two vibrating particles.

➠ Two particles executing SHM are said to be in phase, if they cross their respective mean positions at the same time and in the same direction. They are said to be out of Phase, if they cross their respective mean position at the same time but in opposite directions.

$\huge \text{Path\: Difference}$

➠ When a wave propagates through a medium, the particles are at different distances from the source. Then path difference exists between two particles.

➠ Path difference is the difference of distances between two vibrating particles.
