Question

What is the meaning of periodic change? Give examples.

Answer 1

The surroundings we are living in consist of changes that take place continuously. Be it change in weather, humans (growth in humans), or any other living or non-living organism. It is like a transition that occurs in any substance or any object from one form to another.
Complete step by step solution:
Changes can be classified into several types like slow and fast, natural and man-made, reversible and irreversible, or periodic and non-periodic. Some examples of the above changes are the melting of ice, which shows the transformation from a solid state to a liquid state.
So, periodic changes are the changes that tend to repeat or reoccur at the same interval of time periodically. There are infinite examples of a periodic change like a simple pendulum, the change in the position of a simple pendulum can be periodic and sometimes it can also be categorized as cyclic change. Another example is the change of seasons, seasons repeat themselves each year like spring than winter, rain, summer and the cycle goes on.
Some examples are listed below:
High and low tides in the sea.
Changing phases of the moon.
The change of seasons.
Occurrence of day and night as they repeat after every twenty-four hours.
The beating of the heart.
Clock bells every hour.
Period changes in schools can be a periodic change.
Some flowers which have a periodic opening and closing like a sunflower blooms with sunrise and close after the sunset.
Note: Another type of change is non-periodic change. The changes which do not repeat themselves after a regular interval of time are known as non-periodic changes. Some examples of non-periodic changes are natural disasters like earthquakes, cyclones, etc.
