The **period** of a wave is the time it takes to complete one cycle. The unit for a wave period is **seconds**, and it is inversely proportional to the **frequency** of a **wave**, which is the number of cycles of a wave that occur in one **second**.

## Demo

In this tutorial you will learn how to calculate the **wave period**.

The equation is written like this:

$T = { \text 1 \; \text / \; \text f}$

## Chilled practice question

Calculate the **wave period** for a wave with a **frequency** of 2 **KHz**.

## Frozen practice question

Calculate the **frequency** for a **wave** with a time **period** of 20 **seconds**.

## Science in context

The** period** of a **wave** is the **time** it takes to complete one cycle. The unit for a **wave period** is **seconds**, and it is inversely proportional to the **frequency** of a **wave**, which is the number of cycles of a wave that occur in one **second**.
