Description

The physics of vibrations and waves is a branch of general physics that studies physical phenomena characterized by cyclical changes in physical quantities in time and space. Oscillations are called processes in which the movements or states of a system are regularly repeated in time. The oscillating process is most clearly demonstrated by the swinging pendulum, but oscillations are characteristic of almost all natural phenomena.
