alleryInside a crystal, no two electrons see the same pattern of:
ASurrounding charges
BReflected photons
CMagnetic domains
DThermal vibrations
Answer & Solution
Correct answer: A. Surrounding charges
1. Each electron occupies a unique position in the lattice.
2. Its neighbours are arranged differently from any other's.
3. So no two see the same pattern of surrounding charges.
