What is optics? Optics is the study of visible light and the ways in which visible light interacts with the eye to produce vision.
Law of Reflection Law of Reflection- states that the angle of reflection equals the angle of incidence
Regular Reflection Regular Reflection- the reflection of parallel light rays all in the same direction Occurs on smooth surfaces
Diffuse Reflection Diffuse Reflection- the reflection of parallel light rays in many different directions Occurs on surfaces that are not smooth Some may feel smooth to the touch (like paper), but are actually full of texture
Shape determines how mirrorsform images An image is a picture of an object formed by light. Flat mirrors show an image that looks exactly like you. Convex mirrors (curved outward) the image will appear smaller than you. Concave mirror (curved inward) Far way- image upside down and smaller Close up- right-side up and bigger
Focal Point Focal point- the point at which the rays meet http://www.schooltube.com/video/9b9e3e3cf65c21bb4c 3d/Bill-Nye-The-Science-Guy-on-Light-Bending- Bouncing-Full-Clip
