A beam of light strikes a glass sphere of diameter `15 cm` convering towards a point `30 cm` behind the pole of the spherical surface. Find the position of the image, if `mu` of glass is `1.5`.

A glass sphere of diameter 20 cm is constructed with a material of refractive index 1.5. A beam of light strikes the sphere and converges at a point 40 cm behind the pole of a spherical surface. Find the position of the image.

A long glass rod has a hemispherical end. A narrow beam of light is incident on the spherical end, the beam being parallel to the length of the rod. What is the position of the image formed if the refractive index of glass is 1.5 and the radius of curvature of the spherical surface is 10 cm ?

There is a spherical glass shell of refractive index 1.5, inner radius 10 cm and outer radius 20 cm. Inside th espherical cavity, there is air. A point object is placed at a point O at a distance of 30cm from the outer spherical surface. Find the final position of th eimage as seen eye.

A spherical glass vessel has a cylindrical neck 7 cm long and 4 cm in diameter. The diameter of the spherical part is 21 cm. Find the quantity

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)

An object is placed 50 cm from the surface of a glass sphere of radius 10 cm along the diameter. Where will the final image be formed after refraction at both the surfaces ? mu of glass =1.5 .

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 mark placed on the surface of glass sphere is viewed through glass from an oppositely directed position. If the diameter of the sphere is 30 cm, locate the image of the mark. For glass, mu = 1.5

A glass hemisphere of radius 10 cm and mu=1.5 is silvered over its curved surface. There is an air bubble in the glass 5 cms from the plane surface along the axis. Find the position of the images of this bubble seen by observer looking along the axis into the flat surface of the atmosphere.
