Which optical instrument uses two lenses of short focal lengths to magnify tiny objects, where the objective lens forms a real image and the eyepiece acts as a magnifier?

💡 Solution & Explanation

A compound microscope employs two distinct convex lens systems of short focal lengths, where the objective lens creates a real inverted image magnified by the eyepiece. Simple microscopes use only a single magnifying glass, whereas astronomical telescopes are built with long focal length objectives to view distant celestial bodies. Optical instruments form a high-yield topic in general science physics.
