A transparent cube of $15 cm$ edge contains a small air bubble. Its apparent depth when viewed through one face is $6 cm$ and when viewed through opposite face is $4 cm$ . The refractive index of material of cube is

Options:

Answer:

Solution:

Here, real depth, $x = 15 cm$ apparent depth, $y = 6 + 4 = 10 cm$ $μ = \frac{x}{y} = \frac{15}{10} = 1.5$
