  9. 10. <ul><li>The concave mirror is the inside of the spherical surface is the reflecting surface. </li></ul><ul><li>The characteristic of concave mirror to collect of rays or CONVERGEN </li></ul><ul><li>The cut point of focusing reflected rays mentioned FOCUS LENGTH </li></ul>DEFINING OF CONCAVE MIRROR
  10. 11. The parts of concave mirror F C V C = center of mirror curve or radius of curvature F =the mirror focal point or focal length V = the mirror vertex FV = the distance of mirror focal length CV= the mirror radius
  11. 12. The principle rays of concave mirror <ul><li>A ray parallel to the mirror axis is reflected passes through the focal point of a concave mirror </li></ul><ul><li>A ray that passes through the focal point of concave mirror is reflected parallel to the mirror axis . </li></ul><ul><li>3. A ray that proceeds along a radius of the mirror is reflected back along its original path. </li></ul>
  12. 13. F V 1. A ray parallel to the mirror axis reflected passes through the focal point of a concave mirror
  13. 14. F V 2. A ray that passes through the focal point of concave mirror is reflected parallel to the mirror axis
  14. 15. F V 3. A ray that proceeds along a radius of the mirror is reflected back along its original path
  15. 16. Images formed for the following object distance : <ul><li>Inside F ( first room) </li></ul><ul><li>Between C and the focal length ( second room) </li></ul><ul><li>Beyond the center of curvature C (third room) </li></ul><ul><li>At Focal (F) </li></ul><ul><li>At the radius of curvature (C). </li></ul>
  16. 17. TERUS ULANG F C Images formed at C The nature real, inverted, the same size at the radius of curvature C
  17. 18. F C Images formed at inside F ( first room) The nature virtual, erect, enlarger at IV room
  18. 19. F V Images formed between C and the focal length F( second room) The nature real, inverted, enlarger at III room
  19. 20. F C Images formed beyond the center of curvature (third room) The nature real, inverted, diminished at II room
  20. 21. F C Images formed at F No image will be formed ( the image distance is infinite)
