A monochromatic light is travelling in a medium of refractive index n 1 6 It enters a stack of glass layers from the bottom side at an angle 0 30 The interfaces of the glass layers are parallel to each other The refractive indices of different glass layers are monotonically decreasing as n n man where nm is the refractive index of the mh slab 0 1 see the figure The ray is refracted out parallel to the interface between the m 1 th and mh slabs from the right side of the stack What is the value of m th and An m m 1 13 321 2 1 n mAn n m 1 An n 3An n 2An n An n
