Study Notes
Pinhole Cameras
- Light is emitted from every point on a light source in all directions.
- Light travels in straight lines.
- A small pinhole only allows light to pass through in one direction from each point on a light source.
- Light rays from one point on a source only light up one part of the screen.
- This creates a clear image of the object on the screen.
- The image produced by a pinhole camera is inverted (upside down and back to front).
