Curvature and refraction problem and solution
WebThis book is an attempt to deal with the basic mathematical aspects of 'Engineering Surveying', i.e. surveying applied to construction and mining engineering projects, and to give guidance on practical methods of solving the typical problems posed in practice and, in theory, by the various examining bodies. WebPhysics questions and answers. 4. A simple rule of thumb for single lenses is that the spherical aberration is minimized when the ratio of the second radius of curvature to the first is -6 . Show that this is the case when one considers an object at infinity and a thin lens of index of refraction, \ ( n=1.5 \). Question: 4.
