Presentation Transcript

  1. Can YOU determine the general characteristics of the “image” • Its location (closer than, further than or the same distance as the object and the mirror) • Its orientation (upright or inverted) • Its size (with respect to the object) • Its type (real or virtual) *Let’s look back and analyse our concave “images”

  2. 10.3(cont’d) – Mirror and Magnification Equations Magnification~ the change in size of an optically produced image

  3. 10.3 summary from text • The reflecting surface of a concave mirror curves inward. • Rays that travel toward a concave mirror, parallel to and near the principal axis, will reflect and pass through the principal axis at the focal point, F. • For an object between the focal point and the concave mirror, the virtual, upright image is larger than the object, and the image distance is larger than the object distance. • For an object between the focal point and the centre of curvature, the real, inverted image is larger than the object, and the image distance is larger than the object distance. • For an object beyond C, the real, inverted image is smaller than the object, and the image distance is smaller than the object distance. • You can calculate the image distance and size using, ~ the mirror equation- and the ~ magnification equation- • Spherical aberration is the distortion of an image in a curved mirror that results when reflected rays from the outer parts of the mirror do not go through the focal point. • Homework: p.427 #1-4
