What's This

This false color image of the head of a fruit fly illustrates the level of detail that electron microscopes are capable of resolving. The magnification of this image is about 200 times. Electron microscopes achieve much greater magnifications than light microscopes by using electrons with wavelengths considerably shorter than those associated with visible light. Light microscopes are capable of maximum magnifications of about 2,000 times, whereas magnifications approaching 1,000,000 times are possible with electron microscopes.
