    • Reflection PLAN MIRROR 1 PLAN MIRROR 2
    • PLAN MIRROR
      • Defining
      • Its parts
      • Shaping of image
      • Exercise
    • PLAN MIRROR
      • Is transparency object which get to reflect of light and has plane surface.
    • dark shine
    • Plan mirror Image
    • object image
    • THE IMAGE CHARACTERISTIC OF PLANE MIRROR
      • Virtual
      • Standing
      • The distance of object = The distance of image
      • Symmetries
      • The image place
    • CONCAVE MIRROR
      • The lesson aim
      • Defining
      • Its parts
      • Special rays
      • Shaping of image
      • Exercise
    •  
      • 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
    • 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
    • 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.
    • F V 1. A ray parallel to the mirror axis reflected passes through the focal point of a concave mirror
    • F V 2. A ray that passes through the focal point of concave mirror is reflected parallel to the mirror axis
    • F V 3. A ray that proceeds along a radius of the mirror is reflected back along its original path
    • 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).
    • TERUS ULANG F C Images formed at C The nature real, inverted, the same size at the radius of curvature C
    • F C Images formed at inside F ( first room) The nature virtual, erect, enlarger at IV room
    • F V Images formed between C and the focal length F( second room) The nature real, inverted, enlarger at III room
    • F C Images formed beyond the center of curvature (third room) The nature real, inverted, diminished at II room
    • F C Images formed at F No image will be formed ( the image distance is infinite)
