Books Books When a ray of light passes from one medium to another, it is refracted so that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocities in the two media. Manual of optics, by J.A. Galbraith and S. Haughton - Page 18

...in air to the velocity of light in that medium, and this constant ratio is numerically equal to the ratio of the sine of the angle of incidence to the sine of the angle of refraction. As the angle of incidence is made to vary, the angle of refraction will also vary, but... ## An Elementary Text-book of Physics: Light

...Wlien light is refracted from one medium into another, then, for any two given media, the ratio of thf sine of the angle of incidence to the sine of the angle of refraction is constant for all values of these angles. This relation between the angles of incidence and refraction... ## Appleton's New Practical Cyclopedia: A New Work of Reference Based ..., Volume 2

...the other end. The rays after refraction are no longer parallel, so that the index of refraction (the ratio of the sine of the angle of incidence to the sine of the angle of refraction) is different for each ray; and the difference of the indices for the extreme rays, at the two ends, is... ## Text-book of Physics

...i(sin1) and RB is the sine of the angle r(sinr). With the adoption of these terms Snell's law is : The ratio of the sine of the angle of incidence to the sine of the angle of refraction has a constant value, provided the media remain the same : sin i , .^ This constant ratio... ## The Great Physicists from Galileo to Einstein

...The law in question is the assertion that, when a ray of light passes from one medium to another, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant characteristic of the pair of media. The law was discovered experimentally by Harriott,... ## Before Newton: The Life and Times of Isaac Barrow

...refracting medium (I:11). (5) The angle of incidence always equals the angle of reflection (11:2). (6) The ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant for any pair of media (I1:4). Barrow briefly justifies these hypotheses by appeal to simple... ## Toward a Formal Science of Economics: The Axiomatic Method in Economics and ...
