Question

The local length
of Convex lens is 50cm If an obje
at a distance of 75cm from the lens then find
image distance and magnification, produced by the lens​

Answer 1

Answer:

lens formula - 1/v - 1/u = 1/f

1/v = 1/f + 1/u

1/ v = 1/50 + 1/ (-75)

1/v = -75+50/3750

1/v = -25/3750

1/v = -1/150

v = 150

magnification = v/ u = 150/-75 = 2 units
