F = fokus s = jarak benda ke cermin s' = jarak bayangan ke cemin 1/f = 1/s + 1/s' 1/15 = 1/6 + 1/s' 1/15 - 1/6 = 1/s' 4/60 - 10/60 = 1/s' -6/60 = 1/s' -6s' = 60 s' = -10 cm M = | s'/s | M = | 10 / 6 | M = 1,6 cm M = | h'/h | 16/10 = h' / 3 48 = 10h' h' = 4,8 cm
bisa di jawabnya di beri jarak ? aku bingung bacanya itu ke kanan semua
f = fokus
s = jarak benda ke cermin
s' = jarak bayangan ke cemin
1/f = 1/s + 1/s'
1/15 = 1/6 + 1/s'
1/15 - 1/6 = 1/s'
4/60 - 10/60 = 1/s'
-6/60 = 1/s'
-6s' = 60 s' = -10 cm
M = | s'/s |
M = | 10 / 6 |
M = 1,6 cm
M = | h'/h |
16/10 = h' / 3
48 = 10h'
h' = 4,8 cm

 f = s.s' / s+s'
15 = 6.s' / 6+s'
90+s' = 6.s'
90= 6s' - s'
90=5s'
s' = 90/5
s' =  18 cm.

s'/s = h'/h
18/6= h'/3
6h'=54
h' = 54/6
h' = 9 cm
