13. A small air bubble is inside a glass cube of side
15 cm. When seeing from the top face, the bubble
appears at a distance of 5 cm and if seen from the
opposite face it appears at 7 cm. Refractive index
of glass is

Refractive index of the glass is 1.25
Explanation:
Real depth / apparent depth = refractive index
h1 / 5 cm = μ => h1 = 5 μ cm
h2 / 7 cm = μ => h2 = 7 μ cm
h1 + h2 = 15 cm = 12 μ => μ = 1.25 cm
- The bubble is in the quarter half of the width of the cube.
- So real depth from h1 one side face is equal to (15 - h1) of the real depth from the opposite face.
