Critical Angle, cont For angles of incidence greater than the critical angle, the beam is entirely reflected at the boundary.
{"Image DocumentName": "Critical Angle, cont For angles of incidence greater than the critical angle, the beam is entirely reflected at the boundary.", "Image ImageDescription": "This ray obeys the Law of Reflection at the boundary. Total internal reflection occurs only when light attempts to move from a medium of higher index of refraction to a medium of lower index of refraction.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
