Descartes third model creates a mathematical equation for the Law of Refraction characterized by the angle of incidence equalling the angle of refraction. The pictorial representation of the above definition is shown as follows. Fracsinisinrconstantmu Where i is the angle of incidence and r is the angle of refraction.
It is defined as n cv where c is speed of light in vaccum and v is velocity of light in the material.
If we take any value of i on the table and apply Snells law we can easily calculate values of r. If you recall the index of refraction for water is 1336. Sin th 2 n 1 n 2 sin th 1 n 1 n 2 1 cos th 1 2. A more complicated illustration of Snells Law proves something that seems intuitively correct but is not obvious directly.
