    Answer:

      θ  = 0.3736

    Explanation:

    For this exercise, how light passes through two media separated by a distance, so its movement is governed by the law of refraction.

                n₁ sin  19 = n₂  sint  θ

               

    let’s use subscript 1 for diamond and sub start 2 for water

                sin θo = n₁ / n₂ sin θ

                sin θ  =\frac{2.1}{1.83} sin 19  0.325                                                                                                                                                                                                                                                                              56

                θ  = 0.3736
