A pinhole camera creates upside-down images due to the principles of optics and how light travels. Here's a simplified explanation:1. **Light Travels in Straight Lines:** Light travels in straight lines, and when it passes through a small hole (like the pinhole in a pinhole camera), it continues to travel in straight lines.
2. **Inverted Projection:** When light from the top of an object enters the pinhole, it travels through the hole in a straight line and strikes the bottom part of the film or image sensor inside the camera. Conversely, light from the bottom of the object strikes the top part of the film or sensor.
3. **Overlap of Light Rays:** Since the light rays from different parts of the object overlap and intersect at the pinhole, they create an inverted (upside-down) projection of the object on the film or sensor. This is because each point on the object sends light rays in all directions, and the pinhole only allows a subset of those rays to pass through.
4. **Formation of Upside-Down Image:** The overlapping and intersecting light rays ultimately create an image on the film or sensor that is flipped upside down compared to the actual object. This is why the image appears upside down when you look at it.
