Question

the focal length of convex lens is 50 cm if an object is kept at a distance of 75 cm from the lens then find the image distance and magnification produced by the lens​

Answer 1

Answer:

Let f=50

U= -75

V=?

1\f=1\v-1\u

1\f+1\u=1\v

1\50+1\-75=1\v

1\50-1\75=1\v

3-2\150=1\v

1\150=1\v

Therefore; v =150
