A light beam in air strikes the surface of water at an angle of 26° with the normal. When it enters the water it bends toward the normal, making an angle of 19° with it. The velocity of light in air is approximately 300,000 km/s. What is the approximate velocity of light in water?
sin i / sin r = Vi/Vr
A. 77,197 km/s
B. 222,803 km/s
C. 278,437 km/s
D. 340,625 km/s
