Jawaban:

Awalnya

s = 12 cm

s' = 36 cm

1/f = 1/s + 1/s'

1/f = 1/12 + 1/36 = 3/36 + 1/36 = 4/36

f = 36/4 = 9 cm

setelah digeser 3 cm

s = 12+3 = 15 cm

f = 9 cm

s' = ?

1/f = 1/s + 1/s'

1/9 = 1/15 + 1/s'

1/9 - 1/15 = 1/s'

5/45 - 3/45 = 1/s'

s' = 22,5 cm

sifat = nyata, terbalik, diperbesar
