Chapter 17 - Light and Image Formation

Announcements Reflection and Refraction Image Formation Final QuestionsReflectionWhen a light ray traveling in one medium encounters aboundary to another medium, part of the incident lightis reflectedReflection of light from a smooth surface is calledspecular reflectionReflection of light from a rough surface is called diffusereflectionA surface behaves as a smooth surface as long as thesurface variations are much smaller than the wavelengthof the incident lightWe will restrict our study to specular reflection and usethe term reflection to mean specular reflectionThe law of reflectionThe angle of reflection θ r is equal to the angle of incidence θ iθ i = θ rLight and Image Formation
