If a mark of size 0.2 cm on the surface of a glass sphere of diameter 10 cm and `mu = 1.5 `is viewed through the diametrically opposite point, where will the image be seen and of what size? (in mm)

A mark is made on the surface of a glass sphere of diameter 10 cm and refractive index 1.5. It is viewed through the glass from a portion directly opposite. The distance of the image of the mark from the centre of the sphere will be

A small object stuck on the surface of a glass sphere (n=1.5) is viewed from the diametrically opposite position. Find transverse magnification.

A small object stuck on the surface of a glass sphere (n=1.5) is viewed from the diametrically opposite position. Find transverse magnification.

A small object stuck on the surface of a glass sphere (mu=4//3) is viewed from the diametrically opposite position find transverse magnification.
