Light behaves like waves, just like ripples on water or sound traveling through air.
Imagine you're at a beach, and you throw a stone into a calm lake. The water starts to ripple out in circles, right? That’s how light works, it moves in patterns called waves that spread out from their starting point.
Like Sound Traveling Through Air
When you talk, your voice makes the air vibrate. Those vibrations travel through the air and reach someone else's ears, that’s why they can hear you. Light does something similar but with light waves instead of sound waves. These invisible ripples can move through space and hit things, like how sunlight reaches Earth from the Sun.
Bouncing and Passing Through
Sometimes light waves act like balls bouncing off a wall, we see this when light reflects off a mirror. Other times, they pass right through things, just like how you can see your hand through a clear glass of water. This wave behavior helps us understand why we can see colors, shadows, and even bend light with lenses in our eyes or glasses.
Light is all around us, it's the reason we can see the world!
