Question

What is a pinhole camera? Draw a neat and labelled diagram to show the formation of an image of a lighted candle by it.​

Answer 1

The pinhole camera is the simplest kind of camera. It does not have a lens. It makes use of a tiny opening to focus all light rays within the smallest possible area to obtain an image, as much clear as possible. The image formed using a pinhole camera is always inverted and real.​
