Jawaban:

Perbesaran total mikroskop adalah 297/6 kali atau 49,5 kali

Penjelasan:

fob = 2 cm

fok = 6 cm

d = 26 cm

Ditanya :

Perbesaran total mikroskop pada saat mata berakomodasi maksimum = ____?

Jawab :

Pada saat mata berakomodasi maksimum, asumsikan siok = -25 cm

1/fok = 1/sook + 1/siok

⅙ = 1/sook - 1/25

⅙ + 1/25 = 1/sook

25/150 + 6/150 = 1/sook

31/150 = 1/sook

sook = 150/31 cm

d = siob + sook

26 = siob + 150/31

siob = 26 - 150/31

siob = 656/31 cm

Jarak benda depan lensa objektif :

1/fob = 1/soob + 1/siob

½ = 1/soob + 31/656

1/soob = ½ - 31/656

1/soob = 297/656

soob = 656/297 cm

Perbesaran lensa okuler :

Mok = PP/f + PP/x

Mok = 25/6 + 25/25

Mok = 25/6 + 1

Mok = 31/6 kali

Perbesaran lensa obyektif :

Mob = |siob/soob|

Mob = |656/31 × 297/656|

Mob = 297/31 kali

Perbesaran total mikroskop :

Mt = Mob . Mok

Mt = 297/31 . 31/6

Mt = 297/6 kali atau 49,5 kali
