An electron microscope can view such objects using an electron beam instead of a light beam. Electron microscopy has proved invaluable for investigations of viruses, cell membranes and subcellular structures, bacterial surfaces, visual receptors, chloroplasts, and the contractile properties of muscles. The "lenses" of an electron microscope consist of electric and magnetic fields that control the electron beam. As an example of the manipulation of an electron beam, consider an electron traveling away from the origin along the x axis in the xy a plane with initial velocity v1 = v,-'I'. As it passes through the region x = 0 to x = d, the electron experiences acceleration a = ax'i + ay'j, where ax and ay are constants. For the case 1/, = 1.76 x 107 m/s, ax = 7.42 x 1014 m/sz, and ay = 1.67 >
