Question

A magnifying glass has a focal length of 8.47 cm. (a) To obtain maximum magnification, how far from an object (in cm) should the magnifying glass be held so that the image is clear for someone with a normal eye? (Assume the near point of the eye is at -25.0 cm.) cm from the lens (b) What is the maximum angular magnification?

Step 1

47 cm Near point of the eye (D) = 25.0 cm \[ u = \frac{25 \times 8.47}{25 + 8.47} \] \[ u = \frac{211.75}{33.47} \] \[ u \approx 6.33 \, cm \] Show more…
