![]() ![]() This is not true, so option E is not our final choice. Reviewing our five answer choices, option E claims that even for TIR a refracted rayĮxists. With no light being refracted across the interface. Under these conditions, the incident ray is completely reflected from the interface, Light ray is equal to the angle of refraction of the refracted ray.įor TIR to occur, a ray of light traveling in a more optically dense material mustĮncounter a less optically dense material at an angle of incidence greater than the Total internal reflection occurs when the angle of reflection of the reflected.The boundary between two media of different densities and the light ray is Total internal reflection occurs when a light ray is completely reflected at.Total internal reflection occurs when a light ray is completely absorbed in an.Same path as the incident light ray but in the opposite direction.

Hand, must be greater than that angle since it is totally internally reflected.Īnswer option B is a correct statement about the green and blue angles indicated onĮxample 6: Choosing the Best Description of Total Internal Reflection The green ray’s angle of incidence, on the other The angle of incidence of the blue ray is visibly smaller than that of the green ray,Ĭonfirming that a given ray’s angle of incidence must be greater than theĬritical angle for the ray to be totally internally reflected.īecause the blue ray is refracted out of the fiber, its angle of incidence must be ![]() Ray’s angle of incidence for one encounter with the fiber’s wall. Reviewing the diagram, we see the blue ray’s angle of incidence and the green Means that, at every encounter with the walls of the fiber, the green ray’sĪngle of incidence is greater than the critical angle. We can say, therefore, that the green ray is totally internally reflected. Green ray remains within the fiber while the blue ray escapes it.
