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 ...

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 ...

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 ...

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 ...

Please provide your email address to receive an email when new articles are posted on . In last month’s issue of Primary Care Optometry News I editorialized about the importance of refraction in ...

When light travels from one substance to another, such as from air to water, it can appear bent due to refraction. This occurs because light travels at different speeds in different materials. When ...

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 ...

In my previous Photography Snapshot, I discussed the importance of light and how it bounces to create images. We discovered that the most primitive form of photography was the camera obscura, which ...
