Also, it can be seen from the figure, that the incident ray and the refracted ray lie on the opposite sides of the normal and all three of them lie in the same plane. Thus, the laws of refraction of light can be deduced by Huygens’ construction of a plane wavefront.

WebHuygen’s principle also sometimes called as Huygens–Fresnel principle states that each point on a given wavefront is a source of secondary wavelets or secondary disturbances. Further, the disturbances originating from the secondary source spreads in all directions in the same way as originating from the primary source. WebJan 30, 2024 · Huygens’s principle states that light is a wave that propagates through space like ripples in water. Hence, the light spread out from a source like a wave in all directions. The locus of points that traveled some distance during a fixed time interval is called a wavefront.

WebJul 24, 2024 · Fermat's principle is actually a least-time principle. What it says is, that out of all possible trajectories between two points, light is going to follow the one that minimizes the time spent traversing that trajectory. WebSnell's law can be derived from Fermat's principle, which states that the light travels the path which takes the least time. By taking the derivative of the optical path length, the stationary point is found giving the path taken by the light.
