Refraction - 3 layers

The light is emitted by the red dot, which is in air. The light enters medium 2, and then continues on to medium 3. Before adjusting either slider, make two predictions. How will the angle of the light in medium 3 be affected by (1) increasing or decreasing the index of refraction of medium 2? (2) increasing or decreasing the index of refraction of medium 3?

Note that you can drag the light source left or right, and you can adjust the index of refraction of medium 2 and medium 3 using the sliders.
