Locate the image of the point object `O`. The point `C` is centre of curvature of the spherical surface.

Locate the image of the point object O in the situtaion shown. The point C denotes the centre of curvature of the separating surface.

Locate the image of the point object O in the situation shown in figure. The point C denotes the centre of curvature of the separating surface.

Light from a point source in air falls on a spherical glass surface mu = 1.5 and R = 20 cm . The image is formed at a distance of 100 cm from the glass surface in the direction of incident light. Calculate the object distance from the centre of curvature of the spherical surface.

In the figure shown , a point object O is placed in air on the principal axis. The radius of curvature of the spherical surfaces is 60 cm. I is the final image formed after all reflections and refractions.

(a) A point object, O is on the principle axis of a spherical surface having a radius of curvature, R. Draw a diagram to obtain the relation between the object and image distances, the refractive indicess of the media and the radius of curvature of the spherical surface.

Two concave mirrors are placed facing each other and have the same centre of curvature. Where will the images of the point source Kept at this common centre of curvature be formed?

A point object is placed in air at distance of 40 cm from concave refrating surface of refractive index 1.5.If rasius of curvature of he spherical urface is 20 cm,calcuulate the position of the image.
