1. LAW OF REFRACTION AT SPHERICAL SURFACE
When light passes from a medium of refractive index μ1 to a medium of refractive index μ2 by a spherical surface of radius of curvature R then the relation between object distance u and image distance v is given by
(1) All distances are measured from the pole (P).
(2) Distances measured in the direction of incident rays are taken as positive.
(3) Distances above the principal axis are taken as positive.
(4) Angles measured from the normal in the anticlockwise sense are positive.
DERIVATION
Suppose AB is the spherical surface which saparates the two medium of refractive index μ1 and μ2 .O and Ι is the position of object and image in medium of R.Ι. μ1 and μ2 repectively
or ,
μ2/v– μ1/u = μ2 − μ1/ R
[For small aperture P & N are the same point]
1.2 Terms related to refraction at spherical surfaces
(A) centre of curvature (C) It is the centre of sphere of which the surface is a part.
(B) Radius of curvature (R) It is the radius of the sphere of which the surface is a part.
(C) Pole (P) It is the geometrical centre of the spherical refracting surface .
(D) Principal Axis It is the straight line joining the centre of curvature to the pole.
(E) Focus (F) When a narrow beam of rays of light, parallel to the principal axis and close to it (known as paraxial rays) is incident on a refracting spherical boundary , the refracted beam is found to converge or appear to diverge [depending upon the nature of the boundary (concave/canvex) and the refractive index of two media] from a point on the principal axis .This point is called focus.
Note :
(1) It is not always necessary that for convex boundary the parallel rays always converge. Similarly for concave boundary the incident parallel ray may converge or diverge depending upon the refractive index of two media,
(2) Laws of refraction are valid for spherical surface .
(3) Pole, centre of curvature, Radius of curvature, Principal axis etc. are defined as spherical mirror except for the focus.
Laws of refraction at curved surface
Ex.1 A small point object is placed at O, at a distance of 0.60 metre in air from a convex spherical surface of refractive index 1.5. If the radius of the curvature is 25 cm, then what is the position of the image on the principal axis ?
Ex.2 The radius of a glass ball is 5 cm. There is an air bubble at 1cm from the centre of the ball, refractive index of glass is 1.5 then find
position of image (i) viewed from surface near the bubble, (ii) viewed from surface farther from the bubble.
Sol. (i) On viewing from the closer surface A (near to object) : The final image is formed at Ι.
