As per your syllabus, for the same convex lens problem (f=+10, u=−15), what is the MAGNIFICATION?

  1. +2
  2. +1/2
  3. −2 (image is twice as tall and INVERTED — real)
  4. −1/2
Show answer and solution

Correct answer: C. −2 (image is twice as tall and INVERTED — real)

As per your syllabus, m = v/u = 30/(−15) = −2. Negative sign indicates inverted real image magnitude 2 indicates twice enlarged.
