Q11MCell StructureFree sample

The size of the measles virus, Morbillivirus, is approximately $150\ \text{nm}$ .

The Mimivirus is approximately $4.5$ times larger than Morbillivirus, whilst the Pandoravirus is approximately $1.5$ times larger than the Mimivirus.

Which viruses can be seen using a light microscope with a maximum resolution of $0.25\ \mu\text{m}$ and using an electron microscope?
