Understanding +4 | -1

The equivalent optical path length of two media in contact of lengths

x_1

and

x_2

of refractive index

\mu_1

and

\mu_2

respectively, is

View answer and explanation

Correct option: A

\mu_1 x_1+\mu_2 x_2

Option A (

\mu_1 x_1+\mu_2 x_2

) is correct because the equivalent optical path length is the sum of the products of the refractive index and the length of each medium.
