Answer:

Pierre de Fermat

The path taken by a ray of light between any two points in a system is always the path that takes the least time. This principle leads to the law of the rectilinear propagation of light and the laws of reflection and refraction. It was discovered by the French mathematician, Pierre de Fermat (1601–65).Rectilinear propagation describes the tendency of Electromagnetic waves (light) to travel in a staight line. Light only deviates from a straight line when the medium it is travelling through changes density. This is called refraction.The rectilinear propagation of light means that light travels in straight lines as a wave. ... In a pinhole camera, the light rays reflecting from the bottom of the object travel in a straight line through the pinhole to the film.
