WebSep 15, 2024 · Solved Examples Example 1. A ray of light travels in water and then enters the glass. The angle of incidence is 30 ∘. The refractive index between the glass water interface is (9/8). Find the refractive index in the glass. Solution: Since the refractive index is equal to n = sin i sin r Thus, 9 8 = sin 30 sin r 9 8 = 1 2 sin r 9 4 = sin r WebSo let me just substitute. If we substitute we get three times 10 to the power eight, that's the speed of light in vacuum, meters per second, divided by one point five. Refractive index by the way has no units. And if you divide it, see what you get. You get three divided by one point five so we get two times, three by one point five is two ...
