Lens magnification for object inside focal length Steps:

• Use lens formula: 1/f = 1/v - 1/u (u negative, f positive for converging lens).
• Object between lens and focus: |u| < f, so image virtual (v negative), |v| > |u|.
• Magnification m = |v/u| = f / (f - |u|), which is >1 but depends on exact |u|.
• Without specific object distance, m varies (e.g., 2 if |u|=f/2; 3 if |u|=2f/3).

Why C is wrong:

• m=3.0 assumes |u|=2f/3, but question lacks exact position.

Why the others are wrong:

• A: m=1.0 occurs at 2f (real image), not inside f.
• B: m=2.0 for |u|=f/2, but unspecified.
• D: m=6.0 for |u|=5f/6, but unspecified.

Not enough information.
