Recent experiments that demonstrate the negative refraction of light could bring a heated scientific debate to a close, and give negative-index materials a positive future Figure 1: Negative-index ...

A light ray is traveling in a transparent material of refractive index 1.51 at an angle of incidence of 38 degrees and approaches a second material of refractive index 1.46. Solve for (a) the angle of ...

A property of a material that changes the speed of light, computed as the ratio of the speed of light in a vacuum to the speed of light through the material. When light travels at an angle between two ...
