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).
