Phase (Φ) : The amount which express at any instant, the displacement of the particle and it's direction of motion is known as the phase of the particle.
If two elements of the medium, at any instant are at the similar distance in the same direction from their equilibrium positions and are moving in the similar direction then they are said to be in same medium e.g. In the following diagram particles 1, 3 and 5 are in similar medium and position 6, 7 are also in same medium.
