What Are Waves?
Waves are movements that travel through water, air, or even solid things. They are created by energy moving through something. You might see waves in the ocean or hear them when you listen to music.
Types of Waves
There are two main types of waves: mechanical waves and electromagnetic waves.
Mechanical waves need something to move through. For example, sound waves travel through air. When you speak, you create sound waves!
On the other hand, electromagnetic waves do not need a medium. This means they can travel through space. Examples include light and radio waves.
How Do Waves Work?
Waves move energy from one place to another. They can be big or small! When you throw a stone in a pond, ripples move away from the spot where the stone landed. These ripples are small waves!
Parts of a Wave
Every wave has parts. These are: crest and trough. The crest is the highest point of a wave, and the trough is the lowest point. Think of waves like hills and valleys!
Waves in Nature
You can find waves in many places. Ocean waves crash on the shore. Sound waves help us hear music. Light waves allow us to see colors. Waves are all around us!
Fun Facts about Waves
Did you know that sound waves travel faster than light waves in some materials? Or that radio waves can travel long distances around the Earth? Waves are really interesting!
