Write down in the table below such phenomena which are either periodic or non-periodic from your own or after discussing with your elders. What incident Periodic or Non-periodic and why? 1. The rotation of a blade of a ceiling fan or table fan. 2. Cars moving on a road. 3. Falling of tree leaves.

Phenomena that happens again and again at particular intervals are called periodic. And phenomena that do not occur at fixed intervals are called non-periodic. What incident Periodic or Non-periodic and why? 1. The rotation of a blade of a ceiling fan or table fan. It is periodic because the motion of blades repeats itself at regular intervals. 2. Cars moving on a road. It is non-periodic because the cars do not move at regular period of time 3, Falling of tree leaves. It is non-periodic because leaves do not fall at regular intervals.

Write down in the table below such phenomena which are either periodic or non-periodic from your own or after discussing with your elders What incident Periodic or Non-periodic and why? 1. Tide and ebb. 2. A snake shedding its skin. 3, Tsunami.

Phenomena that happen again and again at particular intervals are called periodic. And phenomena that do not occur at fixed intervals are called non-periodic. What incident Periodic or Non-periodic and why? 1. Tide and ebb. It is a periodic motion. It is a periodic rise and fall of the surface water. They are caused due to the gravitational force of the moon and sun. It occurs at a fixed interval of time. 2. A snake shedding its skin. The outer layer of a snake's skin is shed periodically, and therefore a temporary layer. It occurs at particular interval of time 3, Tsunami. It is a non-periodic change because it does not repeat after a fixed interval of time.

Write down in the table below such phenomena which are either periodic or non-periodic from your own or after discussing with your elders. What incident Periodic or Non-periodic and why? 1. Leap Year. 2. Waves of a sea. 3. Period in the school for different subjects.

Phenomena that happen again and again at particular intervals are called periodic, and phenomena that do not occur at fixed intervals are called non-periodic. What incident Periodic or Non-periodic and why? 1. Leap Year. It does not occur at regular intervals. Any year that is evenly divisible by four is a leap year. It is no-periodic. 2. Waves of a sea. They are non-periodic changes because they depend on the speed of the air. 3. Period in the school for different subjects. It is a periodic phenomenon. A school period is a block of time allocated for each subject.
