Young's experiment showed that the two slits created an interference pattern with peaks and valleys, similar to the two images seen above, demonstrating light's wave-like behavior. These newer images, however, arose from an experiment (on the left) and computer simulation (on the right) with x-rays instead of visible light.
M.-C.Chen and his collaborators on this work used the double-slit experiment to verify their beam's coherence. For more information about this research, check out the team's paper.
