A spherical refrativng suurface of denser medium `(mu=1.5)` is placed in a rarer medium `(mu=1.3)` .for an object lying in rarer medium at 20 cm from the surface,the virtual image is formed at 60 cm in rarer medium.find out the radius fo cruvature of the surface.

A concave spherical surface of refractive index 3//2 is immersed in water of refracitve index 4//3 .If a piont object lies in water at a distance of 10 cm from the pole of the refracting surfae,calculate the position of the image.Given that radius of curvature of the spherical surface is 18 cm.

What curvature must be given to the bounding surface of a refracting medium (mu=1.5) for the virtual image of an object in the adjacent medium (mu=1) at 10 cm to be formed at a distance of 40 cm?

A spherical convex surface of radius of curvature 20 cm, made of glass (mu=1.5) is placed in air. Find the positon of the image formed, if a point object is placed at 30 cm in front of the convex surface on the principal axis.

For a spherical surface,when refraction takes place from a rarer medium (mu_1) to a denser medium (mu_2) , we write -(mu_1)/u + (mu_2)/v = ( mu_2-mu_1)/R where the symbols have their usual meanings. Now suppose that the object is placed in the denser to the rarer medium . Then, rewrite the above equation.

A point object is placed at the centre of a glass sphere of radius 6 cm and refractive index 1.5.The distance of the virtual image from the surface of the sphere is

Fig.2.100 shows a convex spherical surface with centre of curature C,separating the two media of refractive indices mu_1 and mu_2 . . Draw a ray diagram showing the formation of imge of a point object O lying on the principal axis.Derive the relationship between the object and image distances in terms of the refractie indices of the wo media and the radius of curvature R of the surface.

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 that refractive index of the rarer medium is 1.0 ,while that of the denser medium is 2.0.
