YOUR ANSWER MUST BE WITHIN ONE PERCENT OF THE CORRECT RESULT TO BE MARKED AS CORRECT BY THE SERVER. 001 (part 1 of 2) 4 points An object is 20 . 7 cm from the surface of a reflective spherical Christmas-tree ornament 5 . 77 cm in diameter. What is the position of the image? Correct answer:- 1 . 34853 cm. Explanation: 1 p + 1 q = 1 f = 2 R m = h h =- q p Convex Mirror > f > p > f < q < < m < 1 Let : D = 5 . 77 cm and p = 20 . 7 cm . p is positive since it is in front of the mirror and R is negative since it is behind the mir- ror. A spherical Christmas-tree ornament is a convex mirror, so 1 p + 1 q =- 2 | R | . We are given the object distance, p , and can find the radius of curvature from the diameter, | R | = | D | 2 . Inserting these values into the mirror equation and solving for q , we find q =- 1 4 D + 1 p =- 1 4 (5 . 77 cm) + 1 (20 . 7 cm) =- 1 . 34853 cm ....
