convex lens of focal length 25 cm, what will be
the image distance?​

Answer 1

Answer:

v=50cm

Explanation:

its given that,

                      u= -50,f=25,v=?

                       wkt,1/f=1/v-1/u

                               1/v=1/f-1/u

                               1/v=1/25-1/50

                                1/v=1/50

                                v=50cm
