(Hindi)Optical path
Lesson 7 of 17 • 3 upvotes • 10:04mins
Rajesh Kumar
Optical path is equal to multiplication of geometrical path and refractive index of medium in which light travel. When refractive index close to Unity then geometrical path is equal to optical path . when light goes from vacuum to new medium then frequency of the light wave not changed , frequency always depends on source. on same wavefront phase of different particles has a constant value. phase of light wave change by equal amount whether it covers a distance BC is equal to miyuAD in vacuum or AD in the medium then miyu IAD is known as optical path . hear a b a c e and a d e are different but the optical parts are equal ..the ray having longer geometrical path covers less distance in the lens as compared to the ray having shorter geometrical path.
