Refraction and Snell's Law - A Level Physics

This video introduces and explains refraction and Snell's Law for A Level Physics. We can model the refraction of light as a truck moving from concrete to grass. The part of the truck that crosses the boundary first will slow down before the rest of the truck, effectively turning the truck. Light behaves similarly as it crosses a boundary between two mediums. The refraction of light is given by Snell's Law: n=sini/sinr or sini/sinr=constant Thanks for watching, Lewis This video is recommended for anyone studying A Level Physics in the following exam boards: AQA CIE Edexcel Edexcel IAL Eduqas IB OCR A OCR B WJEC _____________________________________ MY PHYSICS WEBSITES Find even more videos organised by exam board and topic at: GCSE Physics Online ► https://www.gcsephysicsonline.com A Level Physics Online ► https://www.alevelphysicsonline.com MY YOUTUBE CHANNEL Your support in watching this video has been invaluable!
