The phase of vibration at any moment is the state of vibrating particle as regards its position and
direction of motion at that moment.
p) Phase difference Δφ =
2πx Path difference.
λ
q) If the phase difference between two particles is 2 π , then they are said to be in phase. If the
phase difference is π , then they are said to be out of phase.
