The process through which light rays falling on the surface on an object are sent back is called reflection of light. Thus, when light falls on the surface of an object it sends back the light. The ...

In this paper, we describe a novel concept for creating multicolor light reflectors by mimicking the surface structures of tiger beetle shells. We prepared dimpled and multilayered films containing ...

Refraction close refractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens. of ...
