Express your answer in centimeters to three significant figures.

Part D

Find the height of the seed's image.

Express your answer in millimeters to three significant figures.

Explanation / Answer

f = r/2 = 12/2 = 6 cm

s = 15 cm

s' = sf/s-f = 15*6/9 = 10 cm

b) m = -s'/s = y'/y

y' = -10*0.33/15 = -0.22 cm

so image is inverted

it is a real image

c) s' = sf/s-f = 10 cm

d) y' = 10*0.33/15 = 0.22 cm
