The first law of refraction states that the incident rays, refracted rays, and the normal to the interface at the point of incidence, all lie in the same plane. The ratio of the sine of the angle of ...

There are many glorious science-based terms when it comes to surfing. We all talk about swells, of course, the underwater energy that creates a breaking wave. But we'll look at swell angles and ...

Well, OK, not exactly. A beam of light could pass through air all day long (as long as you have a layer of air 26 billion kilometers long) and not deviate a whit. But if the density of that air ...

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. It is ...

Sometimes when you look into a swimming pool it’s difficult to tell how deep the water actually is. If you grab something long, like a stick, you can use it to test the depth of the water. Upon ...

For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays - without the need for artificially manufactured metamaterials. Scientists have long ...

I'll be honest: I didn't know that an iPhone was able to do a lidar scan. (The iPhone 12 Pro, 13 Pro, and iPad Pro can all do it.) When I found out that my phone could, I became obsessed with scanning ...
