Benda yang tingginya 8 cm diletakkan 10 cm di depan cermin cekung dengan jari jari kelengkungan 40 cm. Tentukan: a. Letak bayangan b. Perbesaran bayangan c. Ti

Dik: h = 8 cm, s = 10 cm, R = 40 cm
fokus = R : 2 = 40 : 2
f = 20 cm

Jb.
A) 1/s' = 1/f - 1/s
1/s' = 1/20 - 1/10
1/s' = (1 - 2)/20
1/s' = -1/20
s' = -20 cm ✔

B) M = s'/s
M = -20/10 = -2
M = 2 kali ✔

C) h' = M × h
h' = 2 × 8
h' = 16 cm ✔

D) Benda di ruang 1
Bayangan benda di ruang 4
MAYA, TEGAK, DIPERBESAR ✔


Semoga membantu :))
