# Oscillations MCQs

For your better entry test preparation and better Physics MCQs preparation, in this section, we are going to post Oscillations MCQs.

Oscillation refers to any Periodic Motion moving at a distance about the equilibrium position and repeats itself over and over for a period of time. The example of Oscillation includes up and down of a Spring.

A single oscillation in physics means going through one complete cycle. However, the term oscillation is preferred over the term cycles when cycles are rapidly occurring. The rate at which cycles are occurring through some unit of time is called frequency.
