3. Type Real - image appears in front of the mirror (could be projected onto a screen) Virtual - image appears behind the mirror
4. Size a) Enlarged - image is larger than the object b) Reduced - image is smaller than the object c) Same - image is the same size as the object a) b) c)
5. Attitude a) Upright- image is right-side up b) Inverted- image is upside-down c) Laterally Inverted- image is flipped horizontally a) MIRROR b) MIRROR MIRROR c) MIRROR
9. f Terminology Focal Point (F) - where the light rays meet Vertex - the middle point of a curved mirror Focal Length (f) - the distance from the focal point to the vertex vertex principal axis
10. Concave Mirror Ray Diagrams Ray 1 - travels parallel to the principal axis and reflects through the focal point (F)
11. Concave Mirror Ray Diagrams Ray 2 - travels through the focal point and reflects parallel to the principal axis
12. Concave Mirror Ray Diagrams The point where the two reflected rays converge will be the location of the image
13. Concave Mirror Reflections 4 Cases Object is greater than 2 focal lengths from the mirror (do>2f) Object is between 1 and 2 focal lengths from the mirror (f<do<2f) Object is at the focal point (do=f) Object is between the mirror and the focal point (0<do<f)
21. Convex Mirrors Surface of mirror is curved outward Spreads out light rays (“diverging” mirror) Produces a virtual image that is upright and smaller than the object
