Phase of SHM

• The phase of Simple Harmonic Motion (SHM) is a measure of the position of an oscillator at a particular time relative to its mean position. 
• The phase is often represented as an angle and is a key parameter in the description of SHM.
• In the case of SHM, the displacement of the oscillator from its mean position is proportional to the sine of the angular displacement. 
• The phase of the SHM is defined as the initial value of the angle (measured in radians) at time t = 0. It is usually denoted by the symbol φ.
• The phase of an SHM oscillator is a measure of the relative position of the oscillator with respect to its mean position.
•  If two oscillators have the same amplitude, frequency, and direction of oscillation, but different phases, they will be out of phase with each other.
