A laboratory dish, 20 cm in diameter, is half filled with water. One at a time, 0.49 μL drops of oil from a micropipette are dro
irakobra [83]

Explanation:

Formula for path difference is as follows.

             x = 2tn

and,     refractive index (n) = \frac{\lambda}{2t}

Thickness is calculated as follows.

           Thickness (t) = \frac{volume}{area}

       Area = \pi r^{2}

                = \pi \times (\frac{d}{2})^{2}

                = \frac{0.49 \times 10^{-6}}{3.14 \times 0.01 m}

                = 1.56 \times 10^{-8} m

Now, the refractive index will be calculated as follows.

For drop,      n = \frac{\lambda}{2t}

For B drop,    n = \frac{\lambda}{26t}

So,     n = \frac{640 \times 10^{-9}}{26 \times 1.56 \times 10^{-8}}

            = \frac{640 \times 10^{-9}}{40.56 \times 10^{-8}}

            = 1.5

Thus, we can conclude that index of refraction of the oil is 1.5.
