Equation of a progressive wave is given by . The distance is expressed in cm and time is second. What will the minimum distance between two particles have the phase difference of
4 cm
8 cm
25 cm
12.5 cm
Comparing with ,
we get
Also it is given that phase difference between particles
.
Hence path difference between them
Relation between phase difference and path difference -
Phase difference
-
