Answer:
<h2> The refracted angle is r= 34.47°</h2>
Explanation:
According to snell's law the incident normal and refracted ray at the point of incidence all lie in the same plane
Given
incident angle i= 60°
refracted angle r= ?
index of refraction u= 1.53.
Applying the formula
solving for r
r= 34.47°

Well this is just my opinion but I think because all the plants were gone they cant stop mud from rolling into it. Also when it rains the trees wont suck up the water, that will make it over flow and release into the land or dirt on the outsides of it. Mixing those two gives mud and it can potentially flow back in the river in largeish masses causing the river to mix with the mud makinging it more muddy. Hope this helps :D
