F = 4 cm 
So = 12 cm
Si = ... ?

1/f = 1/so + 1/si
1/4 = 1/12 + 1/si
1/4 - 1/12 = 1/si
3/12 - 1/12 = 1/si
2/12 = 1/si

Jadi, Si = 12 : 2 = 6 cm ..
gak jelas
1/f = 1 per f .. begitu seterusnya ..
1/so 1/si apa ?
so = Jarak benda ..
Si = JArak bayangan ..

1/so = 1 per so ..
1/si = 1 per si
ooo makasih
