Question
Is the magnification equal to the magnifying power in this case? Explain.
✓
Answer
Near point, D = 25 cm Distance where the object is kept, u = 7.14 cm Magnifying power of the lens, $\text{m}=\frac{\text{D}}{\text{u}}$ $=\frac{25}{7.14}$ = 3.5 Here, in this case since the image is formed at the least distance of distinct vision, the magnifying power is equal to the magnitude of magnification.
