Application of the Study\u27s Coordinate of a Straight Line to Geometrical Optics. Part I

In the present paper, the Study\u27s coordinate of a straight line has been introduced into geometrical optics. From the result the law of reflection of light and that of refraction have been expressed respectively as follows : mathematics formula where S_6, S_r, S_b and N are Study\u27s coordinates respectively of the incident ray, reflected ray, refracted ray and normal to the surface of reflection or refraction at the point of incidence, and μ is the index of refraction. For example of application of this method a problem with respect to the curvature of the liner in a prismatic spectrum has been treated
