What would the results of Davisson and Germer's experiment have been if they had used x-rays...?

with a wavelength of 1 angstrom instead of a beam of electrons? (In their experiment, electrons were fired at a crystal of magnesium oxide, and photographic film was used to record the places where the electrons came through the crystal)


a) no x ray would have hit the photographic film


b) an interface pattern would have been seen on film


c) the x rays would have struck the film in a random pattern


d) a pattern consisting of rows of dots would have been seen on the film

What would the results of Davisson and Germer's experiment have been if they had used x-rays...?
Actually horizontal rows would have been seen on the film and there would be a hugley crystal pattern in the middle .
