Question

A light beam is travelling from Region I to Region IV (refer figure) The refractive index in Region I, II, III and IV are $n subscript 0 end subscript comma fraction numerator n subscript 0 end subscript over denominator 2 end fraction comma fraction numerator n subscript 0 end subscript over denominator 6 end fraction text and end text fraction numerator n subscript 0 end subscript over denominator 8 end fraction$ , respectively The angle of incidence q for which the beam just misses entering Region IV is

${s i n}^{- 1} (\frac{3}{4})$
${s i n}^{- 1} (\frac{1}{8})$
${s i n}^{- 1} (\frac{1}{4})$
${s i n}^{- 1} (\frac{1}{3})$

The correct answer is: $s i n to the power of negative 1 end exponent invisible function application open parentheses fraction numerator 1 over denominator 8 end fraction close parentheses$
