A diverging lens of f = -20 cm is 20 cm from an object. Rays appear to diverge from:
A20 cm, same side
B40 cm, other side
C10 cm, other side
D10 cm, same side
Answer & Solution
Correct answer: D. 10 cm, same side
1/v = 1/f + 1/u = -1/20 - 1/20 = -1/10, so v = -10 cm, a virtual image on the object side.
