Negative refraction of light using atoms instead of metamaterials Date: February 14, 2025 Source: Lancaster University Summary: Scientists have demonstrated that negative refraction can be ...

IN preparing an elementary lecture on Light, intended to be given at the Taunton College School, I have had to consider how best to explain the somewhat abstruse principle of optical refraction ...

As sunlight strikes the droplet, it undergoes refraction, which means the light bends as it passes through the water droplet. Inside the water droplet, the light is reflected off the inner surface.
