| Unfortunately, radar beam refraction over the lakes remains poorly understood. |
| The amount of refraction is dependent upon the angle of incidence and the wavelength of the light. |
| The trace causes meaning to shift with each shift in angle of refraction brought about by time or change of mood or understanding. |
| The first is a different refraction for the two polarization components at the lens surfaces, which causes a ray bifurcation at each lens. |
| The optical path difference is directly proportional to the cosine of the angle of refraction through the coating. |
| Negative refraction implies that a converging lens made from negative-index material should have a concave surface rather than a convex one. |
