A glass slab consists of thin uniform layers of progressively decreasing refractive indices refractive index such that the refractive index of any layer is μ-m∆μ. Here μ and ∆μ denote the refractive index of 0th layer and the difference in refractive index between any two consecutive layers, respectively. The integer m=0,1,2,3,…… denotes the numbers of the successive layers. A ray of light from the 0th layer enters the 1st layer at an angle of incidence of 30⁰. After undergoing the mth refraction, the r
