What is a Pinhole Camera? On which principle does it works on?
A pinhole camera is a simple device used to take photographs of stationary objects. It works on the principle that light travels in straight lines.

Define Rectilinear propagation of light-:
The property of light which sates that light travels in straight lines as long as it is travelling in the same medium is called Rectilinear propagation of light
