365068 Deviation of \(5^{\circ}\) is observed from a prism whose angle is small and whose refractive index is 1.5 . The angle of prism is

1 \(7.5^{\circ}\)
2 \(10^{\circ}\)
3 \(5^{\circ}\)
4 \(3.3^{\circ}\)
PHXII09:RAY OPTICS AND OPTICAL INSTRUMENTS

365069 The refractive index of the prism is \({\cot \left(\dfrac{A}{2}\right)}\) and the refractive angle of the prism is \({A}\).The angle of minimum deviation is

1 \({180^{\circ}-3 A}\)
2 \({180^{\circ}+2 A}\)
3 \({90^{\circ}-A}\)
4 \({180^{\circ}-2 A}\)
