Question

A cube of sidev15cm is having an air bubble.the bubble appears at 6cm from one face and at 4cm from opposite face .the refractive index of cube is​

Answer 1

Answer:

Hey Buddy here's ur answer.

Real depth / apparent depth = refractive index

h1 / 6 cm = μ => h1 = 6 μ cm

h2 / 4cm = μ => h2 = 4 μ cm

h1 + h2 = 15 cm = 10 μ => μ = 1.5 cm

The bubble is in the middle 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.
