Unit 13 Extra Credit

Either print this page and complete or (better yet) neatly show your answers on a separate page of paper. All answers must be expressed as complete sentences and/or all work shown to receive credit

  1. Fill in the following table for a concave mirror. The symbol f stands for focal length.

    Object

    location

    Image location

    (relative to vertex, F and C)

    Image Height (<, =, > ho)

    Image Type (real or virtual)

    Image Orientation (upright or inverted)

    4*f

    3*f

    2*f

    1.5*f

    f

    0.5*f

  2. What type of mirror produces a reduced, virtual image and under what conditions does the mirror produce such an image? Explain fully.

     

     

     

  3. What type of mirror produces a magnified, virtual image and under what conditions does the mirror produce such an image? Explain fully.

     

     

  4. What type of mirror produces a reduced, real image and under what conditions does the mirror produce such an image? Explain fully.

     

     

  5. Determine the magnification and height of an image formed from a 3.2-cm tall object if placed 21.8 m from a concave mirror with a focal length of 14.5 cm. PSYW

     

     

     

  6. Determine the magnification and height of an image formed from a 3.2-cm tall object if placed 21.8 m from a convex mirror with a focal length of -14.5 cm. PSYW

     

     

     

  7. Construct a ray diagram for questions #5. Draw a concave mirror, place the object at the appropriate location relative to F and C, and draw rays to locate the approximate location, size and orientation of the image.
