What is phase and epoch?

The argument of the sine function (ωt+φ0) is called as the phase of the simple harmonic oscillator at time t and φ0 is called the initial phase or epoch. ie. at t= o , φ = φ0 and this φ0 is called as the epoch. ie. the displacement of an oscillating body at zero time.

What is initial phase or epoch Class 11?

The initial phase of the oscillating particle is called epoch. Consider a particle executing simple harmonic motion along the Y- axis. A simple harmonic oscillator oscillates about its mean position y = 0 to the maximum distance ‘a’ on both the sides which is known as the amplitude of simple harmonic oscillator.

What is meant by phase of the wave?

Phase specifies the location or timing of a point within a wave cycle of a repetitive waveform. Typically, it is the phase difference between sound waves that is relevant, rather than the actual absolute phases of the signals. Two sound waves that are in phase add to produce a sound wave of greater amplitude.

What is phase in sine wave?

The phase is another measurement of a wave and refers to the point where a wave is in a cycle. It is measured in degrees (0°-360°) or radians (0-2π) and is denoted with the Greek symbol Phi (ϕ). Different points in the phase of a sine wave.

What is the phase of a particle executing SHM?

In a simple language the phase of a particle executing SHM is the address of the location of the particle during SHM and at any time. Normally, the location is measured as the angle (Thetha or Phi) measured from the mean position or the fraction of the time period T of the SHM that has elapsed with respect to mean position.

What is a SHM oscillation?

SHM is an oscillation in which a particle moving in a straight line experiences a force which directs it towards its mean position and the magnitude of the force is proportional to the displacement from the mean position. The argument of the sine or cosine function is called the phase of the particle executing SHM.

What is the phase difference between acceleration and displacement in SHM?

What is phase difference between displacement and acceleration in SHM? Hence phase difference between velocity and acceleration is also pi/2. Displacement in SHM is given by x = A sin (wt) where A is amplitude, w is angular velocity, t is instantaneous time. Phase difference between sin and cos function is 90 degrees or pi/2 radians.

What is phase in simple harmonic motion?

When adding two or more simple harmonic motions, phase is a very important term. In a simple language the phase of a particle executing SHM is the address of the location of the particle during SHM and at any time.
