A point object is placed at O in formt of a glass sphere as show in figure .

Show the formation of image by the sphere .

A point object O is placed slightly above the centre C of a glass sphere as shown in figure. If it is viewed almost normally from above the sphere, its image is seen

- A glass sphere of refractive index mu 2.4 has one half silvered. A point object O is placed in front of the sphere at a distance d as shown in the figure. The value of d for which image of O is coinciding with the object O itself is given by d = kR then value of K will be? Consider paraxial rays approximation to be valid.

If an object is placed at the centre of a glass sphere and it is seen from outside, then prove that its virtual image is also formed at centre.

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

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

A glass hemispher of refractive index 4//3 and of radius 4 cm is placed on a plane mirror. A point object is placed on axis of this sphere at a distance 'd' from O as shown in the figure. If the final image is formed at infinity, then find the value of d in mm .
