According to Snell’s law, the angle of refraction, θr, depends on the angle of incidence, θi, and the ratio of the refractive indices of the two media that make up the interface. If the media have identical refractive indices, there is no refraction and the angle θr=θi. Similarly...
There is a mathematical equation relating the angles that the light rays make with the normal to the indices (plural for index) of refraction of the two materials on each side of the boundary. This mathematical equation is known as Snell's Law and is the topic of the next section of ...
The index of refraction for any medium is a dimensionless constant equal to the ratio of the speed of light in a vacuum to its speed in that medium. There is also a critical angle of incidence at which, if the angle of incidence is greater than the critical angle, all the light is ...
The angle of refraction can be solved for using Snell's Law. By rewriting the equation, one can isolate theta2 on one side of the equation so it can easily be solved for: theta2 = = sin^-1(n1/n2 sin(theta1)) where theta2 is the angle of refraction, theta1 is the angle of...

In this case the only change involves the relationship between the angle of incidence ϕ and the angle of refraction ϕ′ used in the equations. The associated reflectances are shown in Figure 8-4. For internal reflection, Brewster's angle occurs at 33.6°, which exactly corresponds to the...
n = the index of refraction θ = the angle of incident (remember the line perpendicular to the surface of the medium is the normal) To find the speed of light of a medium, use the equation v = c/n , where c is the speed of light in a vacuum. To ...
