Reflection Short Answer Problems

  ALL SOLUTIONS MUST INCLUDE COMPLETELY LABELED DIAGRAM(S)

 1. If the distance between the object and a concave mirror is decreased, what action MUST you perform with the screen (with respect to the mirror) if you wish to again produce a clear distinct image on the screen? EXPLAIN

2. Compare and contrast the VIRTUAL image produced by each of the three types of mirrors discussed in class.  You must have at least two similarities and two differences.

3.  If the image that a mirror produces on a screen is too small for the observers to see clearly, how must you adjust the screen and/or object to enable all in the group to easily and clearly observe the image? Explain, using appropriately labeled diagram.

4.  Why is a mirror capable of forming an upright image one time and an inverted image another?  Explain.

5. Does the magnification with mirrors ALWAYS mean that the image is LARGER than the object?   Substantiate by providing a particular case.

6.  While you are looking into a plane mirror, you start to walk toward the mirror.  Describe in detail what happens to your image.

7. Compare and contrast regular and diffuse reflections, and cite examples of where each takes place.

8. What is the smallest vertical plane mirror that may be used to observe a full-length image of an object? Explain using a completely labeled diagram to assist your explanation

9. If the light rays in a ray diagram may be reversed in direction, are the formulas that we have utilized in this section still valid if the object and the imaged are interchanged?   Explain using a complete and accurately labeled diagram.

10. If a person looks into the angle between two mirrors placed at 90o to one another, does he see himself as others see him or are his features reversed. EXPLAIN IN EXPLICIT DETAIL!!!

11.  List and explain at least three properties of an object that enable a recognizable image to be formed of that object by a reflective surface.  Include labeled diagram(s).

12. What are at least two possible problems that one can experience with spherical reflective surfaces? What does each involve, and how can the problem be resolved?

13.  An inverted image that is three times the size of the object is observed with a mirror.

       (A)  What type of mirror must be utilized?

       (B)  Draw a ray diagram showing appropriate placement of the object and subsequent image location.

 

14.  An upright image that is three times the size of the object is observed with a mirror.

       (A)  What type of mirror must be utilized?

       (B)  Draw a ray diagram showing appropriate placement of the object and subsequent image  location.

 

15.  An upright image that is one-third the size of the object is observed with a mirror.

       (A)  What type of mirror must be utilized?

       (B)  Dray a ray diagram showing appropriate placement of the object and subsequent image location.

 

16.  An real image that is one-third the size of the object is observed with a mirror.

       (A)  What type of mirror must be utilized?

       (B)  Dray a ray diagram showing appropriate placement of the object and subsequent image location.

 

17.  An inverted image that is the same size as the object is observed with a mirror.

       (A)  What type of mirror must be utilized?

       (B)  Dray a ray diagram showing appropriate placement of the object and subsequent image location.
