...elementary, yet lead to results of a less obvious nature. They are as follows; — -1. In all refractions the **ratio of the sine of the angle of incidence to the sine of the angle of refraction, is** constant. 2. If between two refracting mediums a third medium, terminated by parallel svwfocefe, Y><t... | |

...the effect is known by the term " refraction." The angle MBL is the " angle of refraction," and the **ratio of the sine of the angle of incidence to the sine of the angle of refraction is** found to be constantly the same for the same substance, when the medium through which the ray originally... | |
