Watch on YouTubeVideoPinhole camera
A box with a small hole in one side and a translucent screen on the opposite side. Light from an object passes through the hole in straight lines and forms an INVERTED (upside-down) image on the screen.
Why inverted? Light from the top of the object travels DOWN through the hole, hitting the bottom of the screen — and vice versa.
Smaller hole → sharper but dimmer image. Larger hole → brighter but blurrier.
Example
Make a pinhole camera with a shoe box and tissue paper screen. Point it at a bright window and see an inverted image of the view.
💡 Tip:The world's oldest camera is a pinhole camera — no lens needed, just a hole.
