Benda tingginya 2 cm berada didepan cermin cekung pada jarak 5 cm. Jika fokus cermin 10 cm. Hitunglah jarak, tinggi, dan perbesaran bayangan! terimakasih..

H = 2 cm s = 5 cm f = 10 cm dit : s' ; h' ; m ? s' = s x f / s - f = 5 x 10 / 5- 10 = 50 / -5 = - 10 cm m = -s' / s = - (-10) / 5 = 2 x h' = m x h = 2 x 5 = 10
s = 5 cm
f = 10 cm
dit : s' ; h' ; m ?
s' = s x f / s - f
= 5 x 10 / 5- 10
= 50 / -5
= - 10 cm
m = -s' / s
= - (-10) / 5
= 2 x
h' = m x h
= 2 x 5
= 10
