Question

rectilinear propagation and reflection. give a complete note on them​

Answer 1

Answer:

The Rectilinear Propagation of Light describes that Light travels in a Straight Line. A mirror changes the direction of Light that falls on it and it travels in a Straight line Path. Reflection of Light occurs when light bounces off a polished surface.

Answer 2

Answer: Rectilinear propagation of light. Light takes the quickest path between any two points. Therefore, light travels in a straight line. This is known as a rectilinear propagation of light. The rectilinear propagation of light means that light travels in straight lines as a wave. This can be observed in the well-defined shadows formed when an object blocks a light source and through the use of a pinhole camera.
