Suppose you need to image the structure of a viruswith a diameter of 50 nm. For a sharp image, thewavelength of the probing wave must be 5.0 nm orless. We have seen that, for imaging such smallobjects, this short wavelength is obtained by usingan electron beam in an electron microscope. Whydon't we simply use short-wavelengthelectromagnetic waves? There's a problem withthis approach: As the wavelength gets shorter, theenergy of a photon of light gets greater and coulddamage or destroy the object being studied. Let'scompare the energy of a photon and an electronthat can provide the same resolution.For the electron with a de broglie wavelength of 3.5nm, what is the kinetic energy (in eV)?
