Define total internal reflection class 12
WebConsider the below diagram to answer the questions: Angle of incidence = i = 90°-56°=34°. From the law of reflection, angle of reflection = r = i = 34°. Angle made by the reflected ray and the surface = q = 90°-r = 90° … WebJan 21, 2024 · Conditions for Total Internal Reflection of Light: The ray of light should travel through an optically denser medium into an optically rarer medium. The angle of incidence should be equal or greater than the critical angle (i C) for the two mediums. To Show sin iC = 1/ 2μ1. By Snell’s law. 1 μ 2 = sin i /sin r.
