If u is the object distance and v the image distance, which of the following expressions gives the linear magnification produced by a convex lens of focal length f?
Answer Details
Magnification, M = v/u = v (1/u) And for the Lens formula 1/u + 1/v = 1/f =>1/u = 1/f - 1/v ∴M = V(1/u) = V(1/f - 1/v) = v/f - v/v = v/f - 1 ∴M = v/f - 1
