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 ...

Once comfortable with the basics, explore 3D tools such as light targeting and light linking. These enable you to point ...

Light is part of various disciplines, shaping the world as we know it. In physics, it serves as a measure of speed and makes vision, and the recording of images by the eye and camera lens possible.

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 ...
