4.1 optics

• 2.
  What is optics? Optics is the study of visible light and the ways in which visible light interacts with the eye to produce vision.
• 3.
  Law of Reflection Law of Reflection- states that the angle of reflection equals the angle of incidence
• 4.
  Regular Reflection  RegularReflection- the reflection of parallel light rays all in the same direction  Occurs on smooth surfaces
• 5.
  Diffuse Reflection  DiffuseReflection- 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 howmirrors form 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  Focalpoint- 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
