Refractive index 0.0 / 5 ? PhysicsAplications of physicsGCSEAQA Created by: blloob1Created on: 03-05-14 14:04 what is refraction refraction is when waves change dirrection as they enter a different medium 1 of 12 what causes refraction the change in density from one medium to the other which changes the speed of the wave 2 of 12 when waves slow down they bend towards what The normal 3 of 12 what happerns if a wave hits a boundry at 90 degrees i.e. along the normal it will not change dirrection but it will slow down 4 of 12 What happerns when light hits a different medium e.g. plastic or glass some of the light will pas through to the new medium but some will be reflected 5 of 12 For question 5's answer how much is relfected all depends on what Angle of incidence 6 of 12 what dose every transparent matirial have A refractive index 7 of 12 Refractive indexof a medium is the ratio of what Speed of light in a vacuum to speed of light in that medium 8 of 12 what is the refractive index equation N=sin I/sin R 9 of 12 in the refractive index equation what is I Angle of incidence 10 of 12 in the refractive index equation what is N Refractive index 11 of 12 in the refractive index equation what is R Angle of refraction 12 of 12
