1/s1 = 1/f - 1/s0 = 1/10 - 1/12 = 6-5/60 = 1/60 = 60/1 = 60 cm M = s1/s0 =60/12 = 5x 5 = h1/5 h1 = 5 x 5 = 25 cm

Dik : ho = 5 cm so = 12 cm f = -10 cm dit : si dan hi? 1/f= 1/so + 1/si 1/si= 1/f - 1/so = 1/-10 - 1/12 = -6/60 - 5/60 = -11/60 si = -0,18
= 1/10 - 1/12
= 6-5/60
= 1/60
= 60/1 = 60 cm
M = s1/s0
=60/12
= 5x
5 = h1/5
h1 = 5 x 5 = 25 cm
so = 12 cm
f = -10 cm
dit : si dan hi?
1/f= 1/so + 1/si
1/si= 1/f - 1/so
= 1/-10 - 1/12
= -6/60 - 5/60
= -11/60
si = -0,18
hi= M.ho
M=|si/so|
|-0,18/12|
|-0,015|
hi=m.ho
-0,015. 5
