In the experiment, a high-power green laser passed through a ruby cube, illuminated from the side by a blue laser. The green laser increased the ruby’s absorption of the blue light, creating a darker ...

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 ...

The other day I got bored and noticed this weird thing happened when I held my finger up to my eye, so I had to science it and figure it out! Let me know if you try these light-bending experiments too ...

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 ...

How plants optimize photosynthesis under changing light conditions. For research, plants are frequently grown under stable lighting, which does not reflect natural conditions. In a series of ...

A team of scientists at the National University of Singapore have developed a new kind of solar cell that uses the contrast of both light and shade to generate electricity. It works by placing a super ...
