what is oscillation class 8

Oscillation is the repeated back and forth movement between two positions or states of an object. It can be a periodic motion that repeats itself in a regular cycle, such as the side-to-side swing of a pendulum, or the up-and-down motion of a spring with a weight. The oscillating movement takes place around an equilibrium point or a mean value. The maximum distance covered or the height in which the oscillations take place is known as the amplitude, and the time taken to complete one complete cycle is called the time period of the oscillation. The number of oscillating cycles completed in one second is referred to as the frequency, which is the reciprocal of the time period. The tides in the sea and the movement of a simple pendulum in a clock are some of the most common examples of oscillations. The vibrations caused by the guitar strings and the other instruments having strings are also examples of oscillations.
