Light
Light is an important part of our daily lives. Light is something that we humans definitely need. But a lot of us take it for granted, and only remember it in the middle of a science lesson. But what exactly is light? That is what I will explain today. I will explain about what is light, its speed, and some strange facts about light. First of all, if we want to know about light, we need to know what it actually is. Light is well known as a wave in the electromagnetic spectrum, but some people think that light is a particle. Nobody knows for sure. This causes the wave-particle duality of light. Light behaves as a wave, but in some ways also behaves as a particle.
