Answer:
critical angle = 64.79°
ray will not penetrate into the water
Explanation:
given details
refractive index of oil n1 = 1.47
refractive index of water n2= 1.33
incident angle = 71.4 °
= sin^{-1}(\frac{1.33}{1.47}
critical angle = 64.79°
incident angle > critical angle = reflection
incident angle < critical angle = refraction
In this case, 71.4 > 64.79 therefore it will undergo total internal reflection
therefore ray will not penetrate into the water
