Question

write the difference between oscillation and variations with two examples ​

Answer 1

Answer:

Oscillation is defined as the process of repeating variations of any quantity or measure about its equilibrium value in time. Oscillation can also be defined as a periodic variation of a matter between two values or about its central value.

The term vibration is used to describe the mechanical oscillations of an object. However, oscillations also occur in dynamic systems or more accurately in every field of science. Even the beating of our heart creates oscillations. Meanwhile, objects that show motion around an equilibrium point are known as oscillators.

Examples of Oscillations

Most common examples for oscillation are the tides in the sea and the movement of a simple pendulum in a clock. Another example of oscillation is the movement of spring. The vibration of strings in guitar and other string instruments are also examples of oscillations.

The pendulum moves back and forth and hence it creates an oscillating movement. Mechanical oscillations are called vibrations. A particle being vibrated means it oscillates between two points about its central point.

Likewise, the movement of spring is also oscillation. The spring moves downward and then upward repeatedly and hence it produces an oscillating movement.

A sine wave is a perfect example of oscillation. Here the wave moves between two points about a central value. The height or the maximum distance that the oscillation takes place is called the amplitude and the time taken to complete one complete cycle is called the time period of the oscillation. Frequency is the number of complete cycles that occur in a second. Frequency is the reciprocal of the time period.

F = 1 / T

Where F is the frequency of oscillation

And T is the time period of the oscillation.

Answer 2

Explanation:

Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. The term vibration is precisely used to describe mechanical oscillation. Familiar examples of oscillation include a swinging pendulum and alternating current.

Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point. The oscillations may be periodic, such as the motion of a pendulum—or random, such as the movement of a tire on a gravel road.

for example, the motion of a tuning fork, the reed in a woodwind instrument or harmonica, a mobile phone.
