Question

who was the first person to experiment with the light and discover the rectilinear propagation of light​

Answer 1

Answer:

He traced out the image cast by each point on the luminous body seeing, in the process, the geometry of radiation in three-dimensional terms. In this way, Kepler was able to formulate a satisfactory theory of radiation through apertures based on the rectilinear propagation of light rays.

Quick Reference. 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).
