The direction of oscillation is perpendicular to the direction of the wave Wave speed can be calculated by the following equation Wavelength, frequency, and period follow the same rules of SHM. Wavelength, frequency, period and wave speed.The direction of a wave is defined by the direction of the energy transfer. A rope that is flicked up and down continuously creates a repeating disturbance similar to the shape of a sine/cosine wave.

The magnitude of the restoring force must be proportional to the displacement of the body and acts towards the equilibrium.Ī travelling wave is a continuous disturbance in a medium characterized by repeating oscillations.When the body is displaced from equilibrium, there must exist a restoring force (a force that wants to pull the body back to equilibrium).The difference between two SHMs with the same frequency in terms of their relative position in a cycle measured in radian Number of times the object oscillates per unit time (usually one second) Time taken for one complete oscillation (in seconds) Maximum displacement of the oscillating object Time period, frequency, amplitude, displacement and phase differenceĭisplacement of the oscillating object at a specific time from its equilibrium position.The period is independent of the amplitude of the SHM and can be given by the following equation The spring-mass system, where the mass is initially displaced to produce a periodic motion around the equilibrium positionĪn object undergoes SHM if it experiences a force which is proportional and opposite of the displacement from its equilibrium position.Simple harmonic motion (SHM) is a special type of oscillation. Oscillations are periodic motions which center around an equilibrium position.
