Lesson details
Key learning points
- A pinhole camera is an empty, closed box with a tiny hole on the front face and a screen on the back face.
- Light moves in straight lines from a light source, through the pinhole, to the screen at the back of a pinhole camera.
- Light from each different point on the object falls on a different single point on the screen, forming the image.
- The image produced by a pinhole camera is dim and inverted. Adding more holes produces multiple images.
- Making the hole larger makes the image brighter but blurred. More light passes through the hole in more directions.
Keywords

Common misconception
Light from a lamp moves in parallel rays in a preferred direction towards the observer.
Overtly discuss the direction light rays move from a lamp by considering where light from a lamp can be seen from.
