ANSWER
..........
1. THE SPEED OF THE LIGHT IN THE AIR IS THE
➡️ 299, 792, 458 METRES PER SECOND
......
2. SPPED OF LIGHT IN WATER
➡️
1. max speed of light, which is about 300,000 kilometers per second, and divide it by the refractive index of the material the photos need to travel.
Water has a refractive index of 1.3 , so divide 300,000kps by 1.3 and you get 230,000kps.
2. unaccounted for entropies and frictions usually make actual efficiency less that idea. In our case, the speed and transmission of light is about 5,000 kps less than the ideal calculation.
3. if you are wondering about refraction angles, just think about a straight line, that would be the shortest route with a refraction angle of 1.0 …
4. A refraction angle of 1.3 would be that line, now with very small zig-zag bends in it, to make the trip from point A to point B about 30% longer.
5. That is what is happening when light travels though water. The time it takes for the photon to be captured and released and then sent back on its path by random water molecules it encounters increases it’s “commute time” by 30%
