Calculate the refractive index of the material of an equilateral prism for which the angle of minimum deviation is 60°.(a) \(\frac {\sqrt {3}}{2}\)(b) √3(c) \(\frac {1}{2}\)(d) \(\frac {1}{\sqrt {2}}\)This question was addressed to me in an interview for internship.I need to ask this question from Ray Optics in section Ray Optics and Optical Instruments of Physics – Class 12 |

Answer» CORRECT CHOICE is (b) √3 The explanation: Refractive index of the prism material is μ = \( \frac { \{ SIN \frac {(A+\delta_m)}{2} \} }{ \{sin \frac {A}{2} \} }\) μ = \( \frac { \{ sin \frac {(60^o+60^o)}{2} \} }{ \{ sin \frac {60^o}{2} \} } \) μ = √3. |
