If light enters a tank at an angle of 35 degrees, 48 degrees is refracted, which is the retraction?
We returned in the same light address where it is initialized, but what if the light suffers hapenns refraction?
I guess the light enters the water through the glass as the incidence refracted angle is less than also taking refrative index of 1.66 and 1.33 as a glass of water as what is the question then? How light can also return where does it arise? That depends on the configuration.
