In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...

There are few things that bother me more than bad lighting–in the living room, the kitchen, and especially when I’m working at a desk. When I’m drawing, I’m annoyed to no end when shadows obscure my ...

Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening new possibilities for technologies that could use a laser beam to control ...

SAN FRANCISCO (KGO) -- A strobe light and a giant phosphorescent screen offer endless posing possibilities in the popular Exploratorium exhibit, "Shadow Box." Inside the Shadow Box, visitors can ...

A team of scientists has found that the narrow beam of a laser, under specific conditions, can cast a shadow — a counterintuitive finding that could open the doors for new applications of optical ...
