If you want to learn sound and light then you are at the right place as we will guide you through it all.
Sound:
The sound is a type of energy that is produced when something vibrates. For example, when you put on songs on the stereo speaker, it creates sound and you hear the music you want to.
Light:
Light is basically made up of waves that travel from different light sources. What actually happens is that light goes to the objects first and then it bounces off towards our eyes which is when we start seeing things.
These are the basics you will learn in science for kids and you can even look upon science for kids videos on the internet for more examples and explanations about how light and sound works.
