An electron is accelerated through a potential difference of 150 V before it strikes a nickel crystal whose interplanar spacing is 0.091 nm.
(i) Calculate the de Broglie wavelength of the electron, giving your answer to two significant figures.
(ii) State whether first-order diffraction from these planes is likely to be observed.
