bantuin ya kakk.. pr untuk besok

3.
So = 6cm
f = 5cm
•a. Karena So lebih dari fokus dan kurang dari 2fokus, maka So berada di R2
•b. 1/f = 1/So + 1/Si
1/5 = 1/6 + 1/Si
1/Si = 1/5 - 1/6
1/Si = 6/30-5/30 = 1/30
Si = 30cm
•c. Benda di R2, sifat bayangan = nyata, terbalik, diperbesar

4.
ho = 2cm
So = 15cm
2f = 10cm
f = 5cm
•a. Karena So lebih dari 2fokus, maka So berada di R3
•b. 1/f = 1/So + 1/Si
1/5 = 1/15 + 1/Si
1/Si = 1/5 - 1/15
1/Si = 3/15 - 1/15 = 2/15
Si = 7,5cm = R2
•c. Benda di R3, sifat bayangan = nyata, terbalik, diperkecil

5.
So = 6cm
f = 5cm
1/Si = 1/f + 1/So
1/Si = 1/5 - 1/6
1/Si = 6/30 - 5/30 = 1/30
Si = 30cm

6.
ho = 2cm
So = 15cm
2f = 10cm
f = 5cm
•a. f = 5cm
•b. 1/Si = 1/5 - 1/15
1/Si = 3/15 - 1/15 = 2/15
Si = 7,5cm
•c. [[ Entar dulu nunggu d]]
•d. M = Si/So = 7,5/15 = 1/2
•c. M = hi/ho
1/2 = hi/2
hi = 1cm
