Total Internal Reflection 0.0 / 5 ? PhysicsMedical PhysicsGCSEAQA Created by: EllieCreated on: 23-04-14 16:55 Carry visible light over long distances Optical fibres 1 of 10 Optical fibres work because of total internal reflection 2 of 10 Total internal reflection only works when light travels from a ... material to a ... material dense less dense 3 of 10 If the angle of incidence is less tahn the critical angle a little bit of the light is internally reflected 4 of 10 If the angle of incidence is greater than the critical angle no light comes out, it's all internally reflected 5 of 10 A dense material with a high refractive index has a low critical angle 6 of 10 a machine used to see inside the body, made of optical fibres Endoscopes 7 of 10 What do the two tubes in an endoscope provide? light and image 8 of 10 endoscopes use .... images real 9 of 10 endoscopes are used in what type of surgery? keyhole 10 of 10
