Explanation / Answer

Here,

radius of curvature , r = 9 cm

focal length , f = 9/2 = 4.5 cm

part B)

object distance , do = 18 cm

ho = 15 mm

Uisng mirror formula

1/f =1/di + 1/do

1/4.5 = 1/18 + 1/di

di = 6 cm

Now , hi/ho = -di/do

hi/15 = -6/18

hi = -5 mm

the image height is 5 mm

part C)

for do = 9 cm

Uisng mirror formula

1/f =1/di + 1/do

1/4.5 = 1/9 + 1/di

di = 9 cm

the image distance is 9 cm

part D)

Now , hi/ho = -di/do

hi/15 = -9/9

hi = -15 mm

the image height is 15 mm

part E)

for do = 2.25 cm

Uisng mirror formula

1/f =1/di + 1/do

1/4.5 = 1/2.25 + 1/di

di = -4.5 cm

the image is located at -4.5 cm from mirrora
