-12 points CJ9 25.P.017 As an aid in working this problem, consult Concept Simulation 25.3. A convex mirror has a focal length of -43.0 cm. A 12.0-cm-tall object is located 42.0 cm in front of this mirror. My Notes Ask Your (a) Using a ray diagram drawn to scale, determine the location of the image. Note that the mirror must be drawn to scale. cm (b) Using a ray diagram drawn to scale, determine the size of the image. (Use a negative sign for an inverted image, positive for upright.) cm .-1.5 points CJ9 25.P.023 My Notes Ask Your Teacher

Explanation / Answer

f = focal length = - 43 cm

ho = height of object = 12 cm

do = object distance = 42 cm

di = image distance

using the mirror equation

1/f = 1/do + 1/di

1/(-43) = 1/42 + 1/di

di = - 21.25 cm

b)

using the formula

hi/ho = - di/do

hi/(12) = - (- 21.25)/(42)

hi = 6.07 cm
