When an electron is accelerated by a voltage difference, the kinetic energy acquired by the electron equals the voltage times the charge on the electron. Thus, one volt imparts a kinetic energy of $1\mathrm{.}602$x$10^-19$ volt$-$coulombs, or $1\mathrm{.}602$x$10^-19$ J$.$ What is the wavelength for electrons accelerated by $1\mathrm{.}400$x$10^3$ volts? $($Mass of electron is $9\mathrm{.}1095$x$10^-31$ kg$.)$ Wavelength $=$ m
