Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

The film explores the properties of light, including reflection and refraction, through various experiments. It demonstrates how light travels in straight lines, how mirrors can reflect images, and ...

This film demonstrates the measurement of the speed of light in both air and water using experimental setups. The first experiment involves measuring the time it takes for light to travel a known ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...
