(6) Microscopes are inherently limited in resolution by the wavelength they use. How much smaller detail can be resolved, with an electron microscope that uses electrons that have been accelerated through a potential difference of 20 million volts, than with a visible-light microscope that uses red light, with A=5.0 x 10-7 m? (Recall that U = qV, where U = electric potential energy, q electron charge and V = the potential difference. Assume both microscopes are observing objects that are at the same object distance of 1 cm from the objective lens of the visible-light microscope or screen, for the electron microscope.)
