Pinhole Camera

Product Detail
A Pinhole Camera is a simple optical device that demonstrates the fundamental principle that light travels in straight lines (rectilinear propagation). It is the most basic form of a camera, consisting of a light-tight box with a tiny hole on one side and a viewing screen on the opposite side.
Operating Principle:
Rectilinear Propagation: Light rays from the top of an object travel in a straight line through the pinhole and land at the bottom of the screen. Conversely, rays from the bottom land at the top.
Image Characteristics: The resulting image is real, inverted (upside down), and faint.
No Lens: Unlike modern cameras, it does not use a lens to focus light. Instead, the small size of the hole ensures that only a narrow beam from each point on the object reaches a specific point on the screen.
