2. A pinhole camera is a simple camera made from a box with a tiny hole, and no lens, that makes an upside-down picture inside. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/P/pinhole/#m2)

### In the lessons

In science lessons about light, pupils make a pinhole camera from a box or tube with tracing paper at the back: light travels in straight lines through the pinhole, so the picture appears upside down. During a solar eclipse, people use a pinhole viewer to look at the sun safely, never looking straight at it. Phrases: «pinhole camera», «pinhole viewer».

### Examples

- Light travels in straight lines through the pinhole. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/P/pinhole/#x6)

### Note

Countable; one word. Safety: never look at the sun directly, not even through a pinhole; a pinhole viewer projects the image onto paper. The picture is upside down because light rays cross at the hole.
