PhysicsEasy105×since 2002Q7109The speed of light in media 'A' and 'B' are 2.0×10102.0 \times {10^{10}}2.0×1010 cm/s and 1.5×10101.5 \times {10^{10}}1.5×1010 cm/s respectively. A ray of light enters from the medium B to A at an incident angle 'θ\thetaθ'. If the ray suffers total internal reflection, thenAθ=sin−1(34)\theta = {\sin ^{ - 1}}\left( {{3 \over 4}} \right)θ=sin−1(43)Bθ>sin−1(23)\theta > {\sin ^{ - 1}}\left( {{2 \over 3}} \right)θ>sin−1(32)Cθ<sin−1(34)\theta < {\sin ^{ - 1}}\left( {{3 \over 4}} \right)θ<sin−1(43)Dθ>sin−1(34)\theta > {\sin ^{ - 1}}\left( {{3 \over 4}} \right)θ>sin−1(43)Check answerSkip
