Labels:crt screen | dialog box | hakham | sky | window OCR: Physical properties of Quartz Chemical/Optical Characteristics Quartz crystals exhibit property called the piezo electric effect That they produce an electric voltage when subiected to pr essure along certain directions of the crystal. Because of this property Quartz crystals have important applications in the electronics industry by controlling the frequency of radio wav es. Quartz also has the optical property of rotatina the plane of polarized light, thereby makina it useful for polarizing microscopes. 28 Qucrtz electrio subjected ortant Jstry Freai uency alsc optica propert rotatino usefu
