How does a camera turn light into a picture?
You press a button, and click — the camera freezes a moment forever. But here's the wild part: a camera doesn't actually "grab" anything. It just catches light. So how does light — invisible, weightless, flying through the air — turn into a picture you can hold in your hand or see on a screen?
Light bounces off everything around you. It hits the dog, the rug, the wall, and ricochets in every direction like a million tiny rubber balls. Some of those bouncing light rays fly straight into your camera's lens. The lens is a curved piece of glass, and its job is to bend all those scattered rays and aim them toward one spot inside the camera.
