A small air bubble is inside a transparent cube of side length 24 cm and of refractive index `4/3` If the apparent distance air bubble from a face is 9 cm then its apparent distance from opposite face is

A small air bubble is trapped inside a transparent cube of size 12 cm . When viewed from one of the vertical faces, the bubble apears to be at 5 cm . From it. When viewed from opposite face, it appears at 3 cm from it.

There is a small air bubble at the centre of a solid glass sphere of radius 'r' and refractive index mu . What wil be the apparent distance of the bubble from the centre of the sphere, when viewed from outside?

An air bubble inside water. The refractive index of water is 4/3 . At what distance from the air bubble should a point object be placed so as to form a real image at the same distance from the bubble:-

A transparent cube of side 210 mm contains a small air bubble. Its apparent distance, when viewed from one face of the cube is 100 mm , and when viewed through opposite face is 40 mm . What is the actual distance of the bubble from the second face and what is the refractive index of the material of the cube ?

A point object is placed in air at a distance of 40 cm from a concave refracting surface of refractive index 1.5. If the radius of curvature of the surface is 20 cm, then the position of the image is –

A small point object is placed at O at a distance of 0.60 metre in air from a convex spherical surface of refractive index 1.5 .If the radius of the curvature is 25cm then what is the position of the image on the principal axis.
