A cube of side 15 cm is having an air bubble. The bubble appears at 6 cm from one face and at 4 cm from opposite face. The refractive index of cube is

An air bubble trapped inside a rectangular glass slab (cuboid) appear at 2 cm from one side and at 3 cm from the other opposite side. If the refractive index of glass is 1.5, what is the actual width of the glass slab?

An air bubble trapped inside a rectangular glass slab (cuboid) appear at 2 cm from one side and at 3 cm from the other opposite side. If the refractive index of glass is 1.5, what is the actual width of the glass slab?

A small air bubble exists inside a transparent cube of side 15 cm each. The apparent of the bubble observed from one face is 6 cm and from the opposite face its apparent distance becomes 4 cm. Determine the real distance of the bubble from the first face and refractive index of the material of the cube.

An air bubble inside a glass slab (mu= 1.5) appears at 6 cm when viewed from one side and 4 cm when viewed from the opposite side. The thickness of the slab is

A small air bubble in glass shpere of radius 2 cm appears to be 1 cm from the surface when looked at, along a diameter. If the refractive index of glass is 1.5 , find the true position of the air bubble.
