Light waves can be bent and reflected to form new and sometimes altered images. Understanding how light rays can be manipulated allows us to create better contact lenses, fiber optic cables, and high powered telescopes. (1) Reflection and refraction Specular and diffuse reflection Specular and diffuse reflection 2 Refraction and Snell’s law Refraction in water […]
