how the pinhole camera works?

- A pinhole camerais a simple camera without a lens and with a single small hole or an opening through which light passes.
- Light from a scene passes through this single hole and projects an inverted image on the opposite side of the box.
- An inverted image is formed in a pinhole camera because the light rays coming from the top and bottom of the object intersect at the pinhole.
- The smaller the hole, the sharper the image up to a certain point, but the projected image is dimmer.
- The human eye in bright light is similar to a pinhole camera.
- The pinhole camera is used to view the images of various objects such as trees, buildings etc.
- It can also be used to take a photograph of an object if a photographic film is placed on the screen.
- The pinhole camera works on the principle that light travels in a straight line.
- The image in a pinhole camera is
- Inverted, i.e. upside down
- Real i.e. can be obtained on the screen
- The same colour as the object
- Smaller, equal or bigger than the object
