Light, Mirrors, and Lenses 7th 3.2 Reflection and Mirrors

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

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

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.
