What is "going on" in the following example?
Understanding the Transmission/Refraction Angle
Where \eta_i and \eta_t denote the index of refraction of the initial medium and transmitting medium, respectively, \bs{n} denotes the normal vector, and \bs{b} is chosen so as to form a basis with \bs{n} (i.e., \bs{b} = \frac{\bs{i} + \cos(\theta_i)\bs{n}}{\sin(\theta_i)}).
