An electron emitted in the beta decay of bismuth-210 has a mean kinetic energy of 390 kev. (a) find the de broglie wavelength of the electron. (b) would such an electron be useful in a davisson-germer type scattering experiment? address this question by determining the angle at which a first-order diffraction maximum would be found using the same nickel target as davisson and germer.
