$14.$ The resolving power of a microscope depends on thewavelength used. If you wanted to see an atom, a resolutionof approximately $1\mathrm{.}00$ x $10-11$ m would be required.$($a$)$ If electrons are used $($in an electron microscope$),$what minimum kinetic energy is required for the electrons?$($b$)$ What If$?$ If photons are used, what minimumphoton energy is needed to obtain the required resolution? $($a$)14\mathrm{.}9$ keV o ignorando la correcci$$n relativista, $15\mathrm{.}1$ keV $($b$)124$ keV
