Also, when the ray of light passes through the prism it bends towards its base. Dispersion of light In 1665, Isaac Newton discovered that white light consists of seven colours.

Intrinsic dispersion in periodic systems sets a fundamental bound for independent selectivity of resonant angles and ...

Details Equipment [1] Overhead projector [1] Prism [2] Sheet of thick cardboard Classroom Assembly Place the cardboard on the projector so that the projector will emit a thin vertical line of light.

From enhancing optical communications to enabling precise chemical and biological characterization, a comprehensive understanding of light’s properties is indispensable.

A project from the Harvard SEAS lab of metamaterials developer Federico Capasso could help address the issue of unwanted light dispersion in optical systems. This could be a particular benefit for ...
