For a spherical refracting surface define:
b. Centre of curvature
c. Principle axis
Asked by Topperlearning User | 21st May, 2014, 01:45: PM
a. Pole : Pole of a spherical refracting surface is the centre of the surface.
b. Centre of curvature: Centre of curvature of a refracting surface is the centre of the sphere of which this surface is a part.
c.Principle axis: The line passing through the pole and centre of curvature of spherical refracting surface, extended on either side is called the principle axis of the surface.

- The interior of a hollow metal sphere is polished to serve as a mirror. At a point 12cm from the centre of the sphere of radius 24 cm, a point source of light is placed. Locate its image formed by two successive reflections, the first reflection taking place at the (a) far wall (b) near wall.
- A convex refracting surface f radius of curvature 20 cm separates two media of refractive indices 4/3 and 1.60. An object is placed in the first medium (n = 4/3) at a distance of 200 cm from the refracting surface. Calculate the position of the image formed.
- The radius of curvature of convex surface is 10 cm and if an object lies at a distance of 20 cm from it in the rarer medium, find the position of the image assuming the refractive index of the rarer medium is 1.0, while that of the denser medium is 2.0.
- A small piece of paper stuck on a glass sphere of 5 cm radius is viewed through the glass from the position directly opposite. Find the position of the image. Refractive index of glass is 1.5
- A point object is placed in air at distance of 40 cm from a concave refracting surface of refractive index 1.5. If radius of curvature of the spherical surface is 20 cm, calculate the position of the image.
