Nurning parallel plastinkadagi yo’li.

102-rasmdagi nurning plastinkaga tushish burchagi plastinkadan chiqib ketish burchagiga teng. qalinligi d va absalyut sindirish ko’rsatkichi n bo’lgan shisha plastinkaning birinchi yog’iga agar nur α burchak ostida tushsa, nur ikkinchi yog’idan x masofaga siljigan xolda va dastlabki yo’nalishidan y masofaga parallel siljigan holda chiqib ketadi. Bu siljishlar quyidagicha topiladi.(AB=d; CD=x; CE=y)
