Question

How does Real depth and Apparent depth help in calculating the refractive index of a medium

Answer 1

Answer:

Real Depth is actual distance of an object beneath the surface, as would be measured by submerging a perfect ruler along with it.

Apparent depth in a medium is the depth of an object in a denser medium as seen from the rarer medium. Its value is smaller than the real depth.
