Phys 1.3 - Refractive Index 0.0 / 5 ? PhysicsLight and OpticsGCSEAQA Created by: DanCreated on: 30-04-13 21:02 What is refraction? Refraction is the change of direction of light as it passes from one transparent substance to another 1 of 10 How does refraction take place? Waves change speed as they cross a boundary 2 of 10 A change in wave speed will also change what? Direction of wave 3 of 10 A change in direction will occur unless? The wave is travelling along the normal 4 of 10 What is a light ray refracted towards? The normal 5 of 10 How much a substance can refract light is a measure of what? Refractive index 6 of 10 What equation helps you work out refractive index? N = SinI / SinR 7 of 10 What is SinI? Angle of incidence 8 of 10 What is SinR? Angle of Refraction 9 of 10 What is N? Refractive Index 10 of 10
