Question

Give the principle,construction and working of a pinhole camera.

Answer 1

A pinhole camera works on the fundamental principle that light always travels in a straight line. For constructing a pinhole camera, a box with a pinhole on one side and a screen on the other side is required. Light from an object enters through the small pinhole and forms an inverted image on the screen. The hole in the box should be small to get a sharer image. if the hole is big, then the image will get blurred.
