Optics: Transmitted Angle, Critical Angle
Original Post (for a table of indices of reflection: http://edspi31415.blogspot.com/2017/12/o...angle.html)
Formulas Used Reflected Angle: θr = θ Transmitted Angel: θt = asin((n1 * sin θ)/n2) Critical Angle: θc = asin(n1/n2), n2 > n1 Perpendicular Frensel Parameters (t, r): t = (2 * n1 * cos θ) / (n1 * cos θ + n2 * cos θt) r = (n1 * cos θ – n2 * cos θt) / (n1 * cos θ + n2 * cos θt) Parallel Fresnel Parameters (t, r): t = (2 * n1 * cos θ) / (n1 * cos θt + n2 * cos θ) r = (n1 * cos θt – n2 * cos θ) / (n1 * cos θt + n2 * cos θ) HP Prime Program FLATOPTIC Code:
