9. Two Kinds of Spherical Mirrors CONCAVE CONVEX

10. KINDS OF SPHERICAL MIRROR 1.Concave Mirror - It reflects light inward to one focal point. It is used to focus light. Also known as converging mirror has a reflecting surface that is recessed inward (away from the incident light).

11. KINDS OF SPHERICAL MIRROR 1.Convex Mirror - Also known diverging mirror is a curved mirror in which the reflective surface bulges towards the light source. Convex mirrors reflect light outwards ; therefore they are not used to focus light

14. 1.Vertex (V) 2.Center of curvature ( C) 3.Radius of curvature ( r) 4. Principal axis (P) 5.Secondary axis (S) 6.Aperture (A) 7.Focus (F ) 8. Focal length (f) Mirror Terminology

15. 1.Vertex (V) – the middle portion/part of the mirror 2. Center of curvature (C) – the center of the sphere of which the curved mirror is a part of 3.Radius of curvature (r) – the distance between the center of curvature (C) and the vertex (V) 4.Principal axis (P) – the line drawn passing through the center of curvature and the vertex Mirror Terminology

16. 1.Vertex (V) – the middle portion/part of the mirror 2. Center of curvature (C) – the center of the sphere of which the curved mirror is a part of 3.Radius of curvature (r) – the distance between the center of curvature (C) and the vertex (V) 4.Principal axis (P) – the line drawn passing through the center of curvature and the vertex Mirror Terminology

17. 5.Secondary axis (S) – any line drawn passing the center of curvature and hitting any part of the reflecting surface of the mirror 6.Aperture (A) – the opening of the mirror 7.Focus (F) - the point where the reflected rays meet 8.Focal length (f) - is the distance between the focus and the vertex. For spherical mirrors with small openings, the focal length is one-half the radius of curvature .

18. Center of Curvature the center of the sphere of which the curved mirror is a part of C P PRINCIPAL AXIS the line drawn passing through the center of curvature and the vertex A APERTURE the opening of the mirror r RADIUS OF CURVATURE the distance between the center of curvature (C) and the vertex (V) VERTEX the middle portion/part of the mirror V FOCUS the point where the reflected rays meet F f FOCAL LENGTH the distance between the focus and the vertex. For spherical mirrors with small openings, the focal length is one-half the radius of curvature

19. HOW TO DRAW RAY DIAGRAMS IN CURVED MIRROR STEPS IN DRAWING A RAY DIAGRAM 1.Pick a point on the top of the object and draw two incident rays traveling towards the mirror 2.Once these incident rays strike the mirror, reflect them according to the two rules of reflection ( convex mirror ) 3.Locate and mark the image on the top of the object 4.Repeat the process for the bottom of the object.

20. DETERMINING THE L-O-S-T OF IMAGE FORMED IN CURVED MIRROR RAY DIAGRAMMING Location of Object: Beyond “C” C F V P IMAGE FORMED L – Bet. C & F O – Inverted S – Reduced T – Real OBJECT

21. DETERMINING THE L-O-S-T OF IMAGE FORMED IN CURVED MIRROR RAY DIAGRAMMING Location of Object: anywhere you put the object in front of a convex mirror L – anywhere you put the object in front of a convex mirror O – upright S – Reduced T – Virtual P F C OBJECT IMAGE FORMED
