Harus diketahui jarak benda awal trus rumusnya
perbesaran = jarak bayangan / jarak benda awal

1/f = 1/so + 1/si
1/2 = 1/so + 1/si
1/2 = 1+1/sosi
1/2 = 2 /sosi
sosi = 2/1/2
sosi= 4
berarti masing-masing so & si nya 4.
teliti :
1/f =1/so +1/si
1/f = 1/4 + 1/4
1/f = 1+1/4
1/f =2/4
f/1 =4/2
f=2 cm. (ketemu)
berarti
M = |Si/So|
M = |4/4|
M = 1 kali.
