1. Of the electron diffraction patterns shown in Figure 1, a is a transmission type pattern from a polycrystalline gold foil in the electron microscope operated at 100 kV. Taking the lattice parameter of gold as 0.40788 nm, Calculate the camera constant from 1.a, assuming a direct scale and identify the metal foils from which b and c originated for the same scale factor (Hint: The metallic elements of b and c are among the group Ag, Pd, Rh, Cr, Rb, V).
