Penjelasan dengan langkah-langkah:
s = 20 cm
r = 60 cm
f = ½r
f = 60

f = 30 cm
1 = 1 – 1
s' f s
s' 30 20
1 = 20 – 30
s' 30 × 20
1 = –10
s' 600
s' = 600

a) s' = – 60 cm
M = s' = 60
s 20
b) M = 3 kali
h = 10cm
h' = s'
h s
h' = 60
10 20
h' = 60 × 10
20
h' = 600
c) h' = 30 cm
Sifat bayangan yang terbentuk :
1) Maya , karena letak bayangan bernilai negatif
2) Diperbesar, karena M = 3
3) Terbalik berada di ruang 4
