...demonstrated in the doctrine of projectiles. It is found by experiment, that when a ray passes out of air into water, the sine of the angle of incidence is to the sine of the angle of refraction, as 4 to 3; and when out of air into glass, as 3 to 2, or rather as 17 to 11, more nearly. And if the passage... | |
