Saturn's rings do cast shadows on the planet. These shadows are hard to see from Earth due to the rings' position and atmospheric interference. The shadows are most visible when the rings are tilted ...

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 ...

In a recent study, researchers from the University of Ottawa have demonstrated a remarkable new phenomenon: a laser beam casting a visible shadow. Typically, photons - light particles - pass through ...

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 ...
