Question

If an object is placed at a distance of 12 cm from a convex lens of focal length 16 cm then calculate the image distance from the lens?

Answer 1

-48cm

Step-by-step explanation:

For a convex lens f is +ve and V is +ve

Using the formula 1/f=1/v+1/u

u=12cm and f=16cm

1/16-1/12=1/v

1/v=-1/48

v=-48cm
