  •   1/f = 1/s + 1/s'
    1/10 = 1/12 + 1/s'
     1/s' = 1/10 - 1/12
     1/s' = 6/60 - 5/60
     1/s' = 1/60
        s' = 60 cm

    M = s'/s
        = 60/12
    M = 5 kali

    Cermun cekung
    f = 10 cm
    s = 12 cm
    m = __?

    perbesaran
    m = f / (s - f(
    m = 10 / (12 - 10)
    m = 10/2 = 5 kali ← jwb
