Question

Tolong dijawab ya, besok dikumpulin makasih... pointnya lumayan nih :)​

Answer 1

s = 20 cm

h = 30 cm

h'= 1/2 x 30 = 15 cm

perbesaran bayangannya

M = 15/30 = 1/2 kali

s'/s = 1/2

s'/20 = 1/2

s'= 10

jarak bayangannya 10 cm

berarti harus menggeser benda = 20 - 10 = 10 cm deket ke cermin
