Which among the following materials is extensively used as a piezoelectric material ?
  1. Quartz
  2. Mica
  3. Amorphous silica
  4. Tridymite

Solution

Piezoelectric materials are materials that have the ability to generate internal electrical charge from applied mechanical stress. Quartz and Rochelle salt demonstrated the highest piezoelectric effects. Hence, option (a) is correct.
