Question

Q. The optical path covered by a light
wave in a particular medium depends upon​

Answer 1

Answer:

refractive index

Explanation:

refractive index decides refractive angle and hence we can find path

Answer 2

Answer:

Refractive Index

Explanation:

The optical path length(OPL) for light passing through a medium with a refractive index $\mu$ is given by = $\mu \times s$. Where s is geometrical path length.

In intregral form we can write as  along path C:

$OPL = \int\limits_C {\mu} \, ds$

The optical path covered by a light wave in a particular medium depends upon​ Refractive Index and Geometrical path (which is constant in most of the cases.
