Light is incident from air on an oil layer at an incident angle of `30^(@)`. After moving through the oil 1, oil 2, and glass it enters water. If the refraction index of glass and water are `1.5` and `1.3`, respectively. Find the angle which the ray makes with the normal in water.   img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/BMS_V04_C01_S01_050_Q01.png" width="80%"
