PHXII09:RAY OPTICS AND OPTICAL INSTRUMENTS

365110 A ray is incident at an angle of incidence i on one surface of a small angle prism (with angle of prism \(A\)) and emerges normally from the opposite surface. If the refractive index of the material of the prism is \(\mu \) , then the angle of incidence is nearly equal to

1 \(2A/\mu \)
2 \(\mu A\)
3 \(\mu A/2\)
4 \(A/2\mu \)

365111 As shown in figure, light is incident normally on one face of the prism. A liquid of refractive index \({\mu}\) is placed on the horizontal face \({A C}\). The refractive index of prism is \({3 / 2}\). If total internal reflection taken place on face \({{AC}, m}\) should be less than \({\dfrac{I \sqrt{3}}{4}}\), where \({I}\) is an integer. Find the valueof \({I}\).
