A small air bubble is inside a cube of 0.21 m. When viewed from one face it seems to be at a depth of 0.06 m, when viewed from opposite face the bubble seems to be at a depth of 0.08m. Determine the actual distance from first face and also the refractive index of the material of the cube.
Q. Illustrate how do you find the refractive index of a liquid by using total internal reflection? Answer:- Using Snell's law n (1) = (n (2) x sin angle (2)) / sin angl
