Question
026 (part 1 of 4) 10.0 points A convex mirror with a focal length of 0.25 m forms a 0.081 m tall image of an automobile at a distance of 0.23 m behind the mirror. a) How far from the mirror is the car located? Answer in units of m 027 (part 2 of 4) 10.0 points b) What is the magnification of the image? 028 (part 3 of 4) 10.0 points c) Describe the image. 1. real, inverted, larger 2. virtual, inverted, larger 3. virtual, upright, smaller 4. real, upright, smaller 5. virtual, upright, larger 6. real, upright, larger 7. real, inverted, smaller 8. None of these 9. virtual, inverted, smaller 029 (part 4 of 4) 10.0 points d) What is the height of the car? Answer in units of mExplanation / Answer
1/u + 1/v = 1/f
1/u + 1/-0.23 = 1/-0.25
1/u = 1/0.23 - 1/0.25
u = 2.88 m
---------------------------------------
b) m = - q / p
m = 0.23 / 2.875
m = 0.08
-------------------------------------
c) image is virtual, upright and smaller
-------------------------------------
d) h0 = hi / m = 0.081 / 0.08
h = 1.01 m
