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 ?
