I am interested in finding out some details concerning vibrations of quartz as it is used in quartz watches. How can I calculate the amount of vibration for a specific size of quartz crystal when an electrical charge is applied? Example: For a 1 cm cubic crystal of quartz, how fast would the crystral vibrate per second and what is the distance traveled by the molecules at the edge of the crystal? How would this change for a crystal that was 1 meter in length? I have been looking at several different sites to try to calculate these details, but have not beed able to find any details on how to calculate this. Any help?
