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
