Jarak fokus cermin 10cm. benda setinggi 5 cm diletakan 20 cm.di depan cermin. tentukan letak bayangan, pembesaran bayangan , tinggi bayangan , sifat bayangan

1/f = 1/s+1/s'
1/10= 1/20 + 1/s'
1/s' = 1/10 - 1/20
1/s' = 2-1 / 20
s' = 20 cm

M = s'/s
M = 20/20
M = 1 x

M = h'/h
1. = h'/5
h' = 5 cm

Sifat Bayangan = Nyata,Terbalik,Sama besar
