What is pin hole camera ?

Dear Student,

A pinhole camera is a simple optical device that forms an image without using a lens or a mirror. A pinhole camera creates a real image of an object because the image can be captured on a screen. The image formed by a pinhole camera is inverted and smaller than the object. A pin-hole camera is used to experiment with image formation by light. An inverted image is formed on the screen of the camera whenever light falls on the small hole. It is used in dark rooms to produce sharp observable images.
