Explanation:
Given:
Thickness of the paperweight cube,
apparent depth from one side of the inbuilt paper in the plastic cube,
apparent depth from the other side of the inbuilt paper in the plastic cube,
Now as we know that refractive index is given as:
- Let the real depth form first side of the slab be,
- Then the depth from the second side of the slab will be,
Since refractive index for an amorphous solid is an isotropic quantity so it remains same in all the direction for this plastic.
Now the refractive index:
