In a crystal, an atom vibrates at a frequency determined by_______________?
Correct answer: C. the stiffness of the bonds it makes with neighbors
- A. the heat content of the crystal
- B. the temperature of the crystal
- C. the stiffness of the bonds it makes with neighbors
Explanation
The natural vibration frequency of an atom in a crystal is mainly set by the stiffness of the interatomic bonds, analogous to a mass-spring system. Temperature changes the vibration amplitude and energy, but not the primary determining factor.
