    For third part just use the simple relation between Birefringence, retardation and thickness .. Here the thickness is 0.05 mm and Birefringence for quartz is 0.009.. So using relation, Retardation (∆) = t×ß where ß is Birefringence and t is thickness.. Putting values we get, Retardation = 0.05×0.009mm = 0.00045mm
