    • Defining
    • Its parts
    • Shaping of image
    • Exercise
  • 3. PLAN MIRROR
    • Is transparency object which get to reflect of light and has plane surface.
  • 4. dark shine
  • 5. Plan mirror Image
  • 6. object image
  • 7. THE IMAGE CHARACTERISTIC OF PLANE MIRROR
    • Virtual
    • Standing
    • The distance of object = The distance of image
    • Symmetries
    • The image place
  • 8. CONCAVE MIRROR
    • The lesson aim
    • Defining
    • Its parts
    • Special rays
    • Shaping of image
    • Exercise
  • 9.  
  • 10.
    • The concave mirror is the inside of the spherical surface is the reflecting surface.
    • The characteristic of concave mirror to collect of rays or CONVERGEN
    • The cut point of focusing reflected rays mentioned FOCUS LENGTH
    DEFINING OF CONCAVE MIRROR
  • 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
  • 12. The principle rays of concave mirror
    • A ray parallel to the mirror axis is reflected passes through the focal point of a concave mirror
    • A ray that passes through the focal point of concave mirror is reflected parallel to the mirror axis .
    • 3. A ray that proceeds along a radius of the mirror is reflected back along its original path.
  • 13. F V 1. A ray parallel to the mirror axis reflected passes through the focal point of a concave mirror
  • 14. F V 2. A ray that passes through the focal point of concave mirror is reflected parallel to the mirror axis
  • 15. F V 3. A ray that proceeds along a radius of the mirror is reflected back along its original path
  • 16. Images formed for the following object distance :
    • Inside F ( first room)
    • Between C and the focal length ( second room)
    • Beyond the center of curvature C (third room)
    • At Focal (F)
    • At the radius of curvature (C).
  • 17. TERUS ULANG F C Images formed at C The nature real, inverted, the same size at the radius of curvature C
  • 18. F C Images formed at inside F ( first room) The nature virtual, erect, enlarger at IV room
  • 19. F V Images formed between C and the focal length F( second room) The nature real, inverted, enlarger at III room
  • 20. F C Images formed beyond the center of curvature (third room) The nature real, inverted, diminished at II room
  • 21. F C Images formed at F No image will be formed ( the image distance is infinite)
