Electron microscopes enable us to see an image with a wavelength as small as 10-9 m. With the help of scanning electron microscopes, we can see fuzzy images of atoms. The half-lives of different atoms can vary widely—some are less than a second, and others are thousands or even millions of years. The steering device directs the bullet particles to their target.
