What do you understand by the term 'phase' of an oscillating particle?

Explanation

The phase of an oscillating particle at an instant is the argument of the sine or cosine function invoved to represent the given oscillatory motion. In an oscillatory motion, `x=asin(omegat+phi_(0)),(omegat+phi_(0))` is the phase of the oscillating particle at the time t. Here, `phi_(0)` is th einital phase or epoch of the oscillating particle.
