Question

Describe the working of a pinhole camera.​

Answer 1

Answer:

A pinhole camera is a simple camera without a lens but with a tiny aperture (the so-called pinhole)—effectively a light-proof box with a small hole in one side. Light from a scene passes through the aperture and projects an inverted image on the opposite side of the box, which is known as the camera obscura effect.

Answer 2

Answer:

When you look at the wall opposite the pinhole, what you will see is an inverted and reversed image of the scene outside. Each point in the scene emits light, and, just like the flashlight, the beam of light from that point passes through the pinhole and creates a point of light on the back wall.
