Refraction & TIR - GCSE Science Required Practical (Triple)

WebRefractive index Light travels at different speeds depending on the medium it is travelling through. It travels quickest through space (or a vacuum) where there are no particles around to slow it down. It travels a little slower in air and even more slowly in denser material such as glass or water. WebLight Waves Notes questions from pages 107 to 117 1. Draw a diagram illustrating the law of reflection. (see page 107) 2. With the aid of a diagram explain how a plane mirror forms an image. also list the properties of this image. (see page 108) 3. (a) What is refraction? (b) Draw a labelled diagram showing how a light ray travels through a rectangular glass block. mixhealthy.com https://getmovingwithlynn.com
