AIIMS 2018 Physics Magnification in Microscopes MCQ Question

In a simple microscope, the magnification (M) is given by the formula $M = \frac{D}{f}$, where $D$ is the distance of the final image from the lens and $f$ is the focal length. Given that the focal length $f$ is 5 cm and the final image is formed at $D = 30$ cm (which is typically the case for a simple microscope), the magnification calculates to $M = \frac{30 \, \text{cm}}{5 \, \text{cm}} = 6$.

Options B (5), C (2), and D (1) are incorrect because they do not accurately reflect the relationship between the image distance and the focal length in this context, leading to lower magnification values than what is achievable with the given parameters.
