Optika Geometri • Part 6: Sudut Kritis & Pemantulan Sempurna

This video contains Geometric Optics material, and this part discusses critical angles and perfect reflection. What is a critical angle and what is the relationship between perfect reflection and critical angle? Everything is discussed in detail in this video, complete with sample questions and their discussions. So make sure to watch this video from start to finish. 00:00 Intro 00:26 Critical Angle and Perfect Reflection 05:18 Example Question 1: Determining the critical angle value of refraction in glass 09:33 Example Question 2: Determining whether perfect reflection occurs on the boundary plane of a prism, and determining the refractive index of the prism so that the right light will be perfectly reflected This video is a continuation of the previous part, so make sure to watch the previous part video first to get a complete understanding.
