Reference no: EM13666060

The planes of atoms in a cubic crystal lie parallel to the surface, 0.87 nm apart. X rays having wavelength 0.41 nm are directed at an angle θ to the surface.

a) For how many values of θ will there be a strong reflection?

b) What is the largest value of θ that gives a strong reflection?

c) What is the second largest value of θ that gives a strong reflection?

d) What energy electrons could give the same result?
