Why do TEM images not form well in crystals with a random arrangement of atoms?
A) With randomly arranged atoms, there is a greater chance that the electrons will miss the atoms, resulting in poor images.
B) Crystals with random arrangements of atoms often have a more reflective surface, so the electrons bounce off the surface of the crystal, resulting in poor images.
C) A random arrangement of atoms in a crystal means that the atoms are extremely small, resulting in poor images.
D) A random arrangement of atoms in a crystal means that the atoms are extremely large, resulting in poor images.
Question 2
