1. Light, Mirrors, and Lenses O 4.2 Reflection and Mirrors

2. Reflection and Mirrors  Law of Reflection – the angle of incidence is equal to the angle of reflection  Diffuse reflection – reflection off of a rough surface  Regular reflection – reflection off of a smooth surface

5. Reflection and Mirrors  Equal distances Object – mirror Image – mirror  Concave mirror )  Convex mirror (  Optical axis – imaginary line down the center of a mirror  Focal point – point where all the light converge

8. Reflection and Mirrors  Focal length – length of the focal point to the mirror  → ), if the object is farther away than the focal point, the image will be upside down  → ), if the object is within the focal point, the image will be right side up  → (, the image will be small.
