WebApr 23, 2024 · $\begingroup$ This is the key point. It's true that viruses can scatter light (as @IamWill suggest), but the features of the virus itself are smaller than visible light waves, so it would not be possible to resolve any features of the virus with visible light. The electron microscope "pictures" of the virus are possible because electrons have a … WebThe maximum resolution of a light microscope is around 0.2 μm, or 200 nm. This means that it cannot distinguish two points closer than 200 nm. One nm, or nanometre, is one billionth of a metre.
