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 ...

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 ...

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 ...

Light is refracted when it enters a material like water or glass. Depending on the density of the material, light will reduce in speed as it travels through, causing it to change direction. Ray ...

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 ...

Welcome to science world! Today, we're going to have a look at a particular type of wave - a light wave. Who knew so many different things travelled in waves? A light wave travels faster than anything ...
