The reflectivity of 2 media is illustrated by the image below. To calculate reflectivity of 2 media, two essential parameters are needed and these parameters are Index of Refraction of Media 1 (n1) and Index of Refraction of Media 2 (n2).
The formula for calculating reflectivity of 2 media:
R = (n2 – n1 / n2 + n1)²
Where:
R = Reflectivity of 2 Media
n1Â = Index of Refraction of Media 1
n2Â = Index of Refraction of Media 2
Given an example;
Find the reflectivity of 2 media when the index of refraction of media 1 is 10 and the index of refraction of media 2 is 20.
This implies that;
n1 = Index of Refraction of Media 1 = 10
n2 = Index of Refraction of Media 2 = 20
R = (n2 – n1 / n2 + n1)²
R = (20 – 10 / 20 + 10)²
That is, R = (10 / 30)²
R = (0.33)²
R = 0.11
Therefore, the reflectivity of 2 media is 0.11.
