Question

how to find v in a convex lens if focal length and magnification given​

Answer 1

Answer:

$\huge\tt\underline {†}\underline\red {Answer}\underline{⇝}$

When a lens of known focal length, f is used to find the relationship between the object distance, u and the image distance v, the value of (1/u + 1/v) is a constant. This constant value is equal to 1/f.
