a. Jarak bayangan (s')
1/f = 1/s + 1/s'
1/15 = 1/20 + 1/s'
1/s' = 1/15 - 1/20
1/s' = 4/60 - 3/60
1/s' = 1/60
s' = 60 cm✓
b. Perbesaran bayangan (M)
M = |s'/s|
M = 60 / 20
M = 3 ✓
c. Sifat bayangan nyata, terbalik, diperbesar.
2.
1/40 = 1/60 + 1/s'
1/s' = 1/40 - 1/60
1/s' = 3/120 - 2/120
1/s' = 1/120
s' = 120 cm ✓
M = 120 / 60
M = 2 ✓
c. Sifat bayangan diperkecil, tegak, Maya.
