A small object is enclosed in a spere of glass 7 cm in radius .It si situated 1 cm from the centre and is veiwed from the side to whh it is nearest.where will it appear to be ,if refractive index is 1.4?Also find the appparent position of the oject as seen by an eye looking laong diameter throug greatest thickness of eh glass.

A glass sphere of radius 5 xx 10^-2 m has a small bubble 2 xx 10^-2m from its centre. The bubble is viewed along a diameter of the sphere, from the side on which it lies. How far from the sphere will it appear? Refractive index of glass 1.5.

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

A small piece of paper stucjk on a glass shpere of 5 cm radius is viewed through the glass from the position directly opposite .Find the position of the image .Refractie index of glass is 1.5.

A small black dot is marked on the surface of a glass spehre (mu=1.5) and is viewed from the other side.If radius of the sphere is 15 cm,find the position of the image of the dot.

Fig.2.49 shows a solid glass sphere of radius 5 cm that has a small air bubble O trapped at a distance 2 cm from the centre C.Th refractive index of the material of glass is 1.5.Find the apparent position of the bubble where it will appear ,when seen throught the surface from an ougtside point E. .

A rectangular glass block of thickness 10 cm and refractive index 1.5 is placed over a small coin.A beaker is filled with water of refractive index 4//3 to a height of 10 cm and is placed over a small block. Find the apparent position of jthe object,when it is viewed at normal incidence. .

An object is placed 21 cm in front of a concave mirror of radius of curvature 10 cm.A glass slab of thickness 3 cm and refractive index 1.5 is then placed close to the irror in the space between the object and mirror as shown in Fig.2.62.Find the position of the final image formed.You may take the distacne of the near surface of the slab from the mirror to be 1 cm. .

A small pin fixed on a table top is viewed from above from a distance of 50cm. By what distance would the pin appear to be raised if it is viewed from the same point through a 15cm thick glass slab held parallel to the table? Refractive index of glass = 1.5. Does the answer depend on the location of the slab?
