the refractive index of the liquid is 1.476
The refractive index, which has no dimensions, measures how quickly light passes through a substance.
It can also be described as the difference between the speed of light in a vacuum and a medium.
Refractive index is equal to the product of the light's liquid and vacuum speeds.
Therefore.
speed of light in vacuum = 4.96 km/t
speed of light in liquid = 3.36 km/t
Refractive index = 4.96/3.36
Refractive index =1.476
Therefore, the refractive index of the liquid is 1.476

Answer:
At a stream's headwaters, often high in the mountains, gradients are steep. The stream moves fast and does lots of work eroding the stream bed.As a stream moves into lower areas, the gradient is not as steep. Now the stream does more work eroding the edges of its banks.
