Sebuah benda tingginya 10 cm berada 8cm di dpn cermin cekung jari jari kelengkunganya 12 cm hitung: a jarak bayangan b jarak fokus c perbesaran d tinggi bayangan e lukiskan f sifat-sifat
raraza
A.s'= 1/f - 1/s = 1/6-1/8=24cm b.jarak fokus = f = r(jari")/2 = 12/2 = 6 cm c. M = s'/s = 24/8 = 3 kali d. M= h'/h = tinggi bayangan ---> h' = Mxh = 3x10 = 30 cm

A. s'= 1/f - 1/s = 1/6-1/8 =24cm b. jarak pokus= f= r/2=12/2 =6cm c. M=s'/s =24/8 =3 kali d. M=h'/h= tnggi byngan => h' = M x H =3 x 10 = 30 cm
b.jarak fokus = f = r(jari")/2 = 12/2 = 6 cm
c. M = s'/s = 24/8 = 3 kali
d. M= h'/h = tinggi bayangan ---> h' = Mxh = 3x10 = 30 cm
=24cm
b. jarak pokus= f= r/2=12/2
=6cm
c. M=s'/s =24/8
=3 kali
d. M=h'/h= tnggi byngan => h' = M x H =3 x 10
= 30 cm
