quartz wedge मीनिंग इन हिंदी

उदाहरण वाक्य

1. The quartz wedge or selenite plate enables us to do this.
2. A quartz wedge also may be calibrated by determining the amount of double refraction in all parts of its length.
3. conoscopic lens, and compensators ( plates of anisotropic materials; gypsum plates and quartz wedges are common ), for crystallographic analysis . ]]
4. If the quartz wedge be passed across it so that the long axis of the wedge is parallel to the axis of elasticity in the section the polarization colors will rise or fall.
5. This design avoids the problems inherent in the basic quartz wedge, where the zero reading coincides with the thin end of the wedge, which is often lost when grinding the plate during manufacture.
6. In addition to modifications of the microscope's optical system, petrographic microscopes allow for the insertion of specially-cut oriented filters of biaxial minerals ( the quartz wedge, order when needed.
7. The quartz wedge, quarter mica plate or selenite plate permit the determination of the positive or negative character of the crystal by the changes in the color or shape of the figures observed in the field.
8. The "'Babinet compensator "', an accessory useful in polarized light microscopy, was built with twin, opposed quartz wedges having mutually perpendicular crystallographic axes, and is still widely employed in microscopy.
9. If now it be used to produce compensation or complete extinction in any doubly refracting mineral section, we can ascertain what is the strength of the double refraction of the section because it is obviously equal and opposite to that of a known part of the quartz wedge.
