Explanation / Answer

011)

R = radius of curvature = 27.4 cm

f = focal length = R/2 = 27.4/2 = 13.7 cm

do = object distance = 21.7 cm

di = image distance = ?

using the mirror equation

1/do + 1/di = 1/f

1/21.7 + 1/di = 1/13.7

di = 37.2 cm

part 2)

magnification is given as

m = - di/do

m = - 37.2/21.7 = - 1.71
