AP B 1998 MC 50 A 001 10.0 points An object, slanted at an angle oF 45 , is placed in Front oF a vertical plane mirror, as shown. Mirror Which oF the Following shows the appar- ent position and orientation oF the object’s image? 1. image 2. image 3. image 4. image 5. image 6. image 7. image 8. image correct Explanation: ±or a plane mirror, the line connecting a point oF the object and the corresponding point oF the image is perpendicular to the mirror, and corresponding distances From the points to the mirror are the same. Thus, the image should be image object Concave Mirror Image 002 10.0 points The real image produced by a concave mirror is Found to be 0 . 342 times the size oF the object. IF the distance From the mirror to the screen on which the image appears is 1 . 15 m, what is the Focal length oF the mirror? Correct answer: 0 . 85693 m. Explanation: 1 p + 1 q = 1 f = 2 R m = h h = - q p Concave Mirror f > 0 >p> f f < q < 0 >m> -∞ f >p> 0 -∞ < q < 0 >m> 1 Let : q = 1 . 15 m and M = - 0 . 342 .
