You might expect that an opaque material will always hinder the transmission of light by absorbing or scattering any light that is shone on it. But by carefully preparing a beam of laser light, ...

Even diffuse objects like clouds or sugar cubes cast shadows, because they’re disordered media that scatter light waves. But now, researchers at TU Wien and Utrecht University have found a way to ...

Light propagating in a layer of scattering nanoparticles, shows the principle of diffusion - like tea particles in hot water. The deeper light is penetrating into the layer, the lower the energy ...

Researchers have found a new way to see through opaque materials with the help of light. This could be done by recording wavelengths from visible light, which can pass through solid material like ...

A transparent substance will allow light to travel through on a straight line, in a turbid substance the light will be scattered numerous times, traveling on more complicated zig-zag trajectories. But ...
