The device operation is based on differential material dispersion in a waveguide array ... is demonstrated experimentally for a dual-color light field, where we achieve a higher than 70% routing ...

This means that the light leaving the prism is spread out into its different colours, a process called dispersion. This experiment is recorded as first being carried out by Isaac Newton ...

This means that the light leaving a prism is separated into its spectrum colours. This a process called dispersion.

Jeff Waldstreicher, a meteorologist with NOAA's National Weather Service, provides this answer. Sunlight passing through raindrops causes rainbows via a process called refraction, which is the ...
