Question

Consider a diverging lens of focal length f--20 cm and a virtual object placed 30 cm from the lens. Find the image distance q

Answer 1

Answer #1

Here ,

f = -20 cm

for the virtual object , u = 30 cm

Using lens formula

1/v - 1/u = 1/f

1/v - 1/30 = -1/20

v = -60 cm

the image distance is -60 cm
