b.M = s'/s = 15/15 = 1 kali
c. nyata,terbalik,sama besar
h = 2,5 cm
s = 15 cm
f = 7,5 cm
dit
s' =....
M =....
sifat....
Jawab
a. jarak bayangan = s'
1/f = 1/s + 1/s'
1/7,5 = 1/15 + 1/s'
1/7,5 - 1/15 = 1/s'
4/30 - 2/30 = 1/s'
2/30 = 1/s'
s' = 30/2
s' = 15 cm
b. perbesaran bayangan = M
M = I s'/s I
M = 15 / 15
M = 1 kali
sifat bayangan
sama besar, terbalik, nyata
berarti benda ada di titik P
semoga membantu sob......
