Penjelasan:
R = 10 cm
s = 10 cm
h = 5 cm
Jarak focus benda :
R = 2f
10 = 2f
f = 5 cm
a. Jarak bayangan
1/f = 1/s + 1/s'
⅕ = 1/10 + 1/s'
⅕ - 1/10 = 1/s'
2/10 - 1/10 = 1/s'
1/10 = 1/s'
s' = 10 cm
b. Perbesaran bayangan
M = |s'/s|
M = |10/10|
M = 1 kali
c. tinggi bayangan
|s'/s| = h'/h
1 = h'/5
h' = 5 cm
d. Sifat bayangan
Nyata, terbalik, sama besar
