Researchers at the University of Glasgow have achieved a milestone in brain imaging by detecting near-infrared light that traveled completely through an adult human head. Using high-powered lasers ...

The double-slit experiment, first performed by Thomas Young in 1801, involves shining a beam of light on a plate or card with two small slits cut into it for the light to pass through. When the ...

Light passing through them would normally interact with them. The photons would be absorbed (creating an atomic excitation) and then reemitted. Overall, the light would gain a group delay.

A celebrated experiment in 1801 showed that light passing through two thin slits interferes with itself, forming a characteristic striped pattern on the wall behind. Now, physicists have shown ...
