A light ray strikes a homogeneous rectangular block of glass of thickness w at an angle i The ray emerges at point B at an angle i see diagram below a Find i in terms of i and show that the emerging and incident rays are prallel b Find the lateral displacement which is the distance d between the incident and emerging rays in terms of angle i the refractive indices n and n and width w of the block c Use the formula obtained in part b to calculate d
