A layer of oil floats on water. A ray of light shines onto the oil with an angle of incidence 30^{\circ}. The refractive indices of oil and water are 1.5 and 1.3 respectively. The ray makes the angle in the water is

Correct Answer is : sin−1(12.6)rad

\sin ^{-1}(\frac{1.3}{1.5}) {rad}

\sin ^{-1}(\frac{1}{2.6}) {rad}
