If a light wave moves from water into seawater in which direction will the bend?

Explanation:

The refractive index of sea water is more than refractive index of water . so when light passes from water to sea water or from low refractive index to high refractive index , ray of light bends towards the normal . This bending is very small because the difference in refractive index is very small.

it should be -8.6 cm hope this out

i think it would be 5
