question

A plate of crystal quartz cut with its faces perpendicular to the optic axis is found to exactly annul the rotation of the plane of polarization of sodium light produced by a 10 cm length of a 20% solution of maltose. Calculate the thickness of the quartz plate. [\delta] for maltose =144°. (Specific rotation is defined as the rotation produced by a 10 cm column of liquid with a 1 gram/cubic centimeter active substance.)
