Homework Statement
In the experiment of Davisson and Germer (a) show that the second- and third-orderdiffracted beams cannot occur and (b) find the angle at which the first-order diffracted beamwould occur if the accelerating potential were changed from 54 to 60 V. (c) What acceleratingpotential is needed to produce a second-order diffracted beam at 50°
I have no idea how to approach this problem...
Homework Equations
Some equations I think would come in use...:
nd=sin(theta)
