Today, I'd like to dive into the use of shadows in landscape photography. Shadows are almost always part of nature: we often shoot using a (almost-)point light source (the sun or the moon), and even ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

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 ...

For the experiment, a high-power green laser was directed through ruby cube and illuminated with a blue laser from the side. The green laser increases the optical absorption of the blue illuminating ...

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 ...
