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.

Can a pinhole camera forms an image which is bigger than the object?
Yes, pin hole camera can form image bigger than the object. Pin hole camera forms real, up side down and the size of the image depends on the distance between the pin hole and the screen on which image is formed. Pin hole camera works on the principle of rectilinear propagation of light.
Why does a pinhole camera form an inverted image?
The light passing through a concave lens produces an inverted image. It consists of a box with a small size hole, which acts as the lens for the pinhole camera. The light enters in a straight line by the aperture from top of the box to bottom. The inverted image of the object is formed inside the box.
