Multiple Choice

A biconvex lens has a focal length of 12 cm. If an object is placed 5 cm from the lens, where is the image formed? Is it real or virtual? Is it upright or inverted? What’s the height of the image if the object is 2 cm tall?

A

s_i = -8.5 cm; Real; Upright; 1.7 cm

B

s_i = -0.117 cm; Virtual; Upright; 1.7 cm cm

C

s_i = -8.5 cm; Real; Inverted; 3.4 cm

D

s_i = -8.5 cm; Virtual; Upright; 3.4 cm
