θ 2 heta_2 θ 2 – Refraction angle in the thin-film.įurthermore, if the refractive index of the first medium is less than the second medium, then there will be a 180 ° ext R p = R p 1 + R p 21 . reflection: i > critical angle Medium one (i)refractive index (ni) Medium two (r)refractive index (nr) Speed 2.d d d – Thickness of the thin-film and To calculate Brewsters angle use the formula B arctan (n2 / n1), where B is Brewsters angle, n1 is the refractive index of the initial medium through which the light propagates and n2 is the refractive index of the other medium.

n 2 n_2 n 2 – Refractive index of the thin-film.Please note that the formula for each calculation along with detailed calculations are available below. To use this online calculator for Index of Refraction, enter Refractive Index of Medium 2 (n2), Refracted Angle (r) & Incident Angle (i) and hit the calculate button. The Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another.If i is the angle of incidence of a ray in vacuum (angle between the incoming ray and the perpendicular to the surface of a medium, called the normal) and r is the angle of refraction (angle between the ray in the medium and the normal), the refractive index. Speed of light waves in the medium of refraction ( C2) m/s. The Austrians score 60, making it a pragmatic culture. Speed of light waves in the incident medium ( C1) m/s. reflection of Austrias high score on the Uncertainty Avoidance Index. O P D OPD OP D – Optical path difference between the two reflected light waves Finally,you can determine the angle of refraction using this value using our reflective index calculator.
