The microscope in cell studies — practice question

Before this, the viruses most widely known to science measured $20$-$150\,\text{nm}$ in size. In 2003, the Mimivirus was discovered, with a size of about $680\,\text{nm}$. In 2013, the Pandoravirus was discovered, and it has a size of more than $1000\,\text{nm}$. Which viruses are visible with both a light microscope with a maximum resolution of $0.25\,\mu\text{m}$ and an electron microscope?
