How does a pinhole camera work class 6?
A pinhole camera is a simple camera, without lens, in the shape of a box. One of the sides has a small hole and it produces an inverted image of the outside world at other side. Smaller the hole, sharper the image. Temporary Black and White images are formed on the screen if a tracing paper is used.
On which principle does a pinhole camera work?
Pinhole cameras rely on the fact that light travels in straight lines – a principle called the rectilinear theory of light. This makes the image appear upside down in the camera.
Why is the pinhole camera painted black?
Light from the object goes through the pinhole and produces an inverted image in full colour on the screen. This is because only light from one point on the object can reach a given point on the screen. You should notice that the inside of the pinhole camera is painted black to stop unwanted reflections inside.
