Reflection and Refraction
Reflection and Refraction When light hits a medium interface: Reflection Refraction Absorption Reflection Any light being reflected will reflect at the same angle from the normal Specular Reflection Reflection produced in a smooth, flat, shiny surface Parallel incident rays produce parallel reflected rays Example Mirror Glass Shiny Metal Polished Wood Granite Still Water Can produce Coherent Image Diffuse Reflection Reflection in rough Flat Surface No Coherent Image Formed Example Painted Walls Asphalt Fabric Wood Refraction Light Travels at different speeds in different media It will curve upon passing from one medium to another
