| Unfortunately, radar beam refraction over the lakes remains poorly understood. |
| The first is a different refraction for the two polarization components at the lens surfaces, which causes a ray bifurcation at each lens. |
| It was a beautifully worked out theory and explained most of the observed phenomena of light such as reflection, refraction, diffraction etc. |
| This offset depends on the angle of incidence, the index of refraction, and is directly proportional to the thickness of the slab. |
| Because he believed that refraction inevitably produced coloured fringes, he advocated reflecting telescopes, and made one. |
| Because of the effect of wave refraction, the plan shape of crenulated coasts can attain an equilibrium state. |
