WXMI — In our science experiment today, we look at a disappearing coin trick, which really is no trick at all. It illustrates density and refraction. Some things are more dense (or heavier) than other ...

GRAND RAPIDS — Every day we see and use light for numerous daily functions, but did you know you can actually bend light? Its called refraction and our experiment today is going to show you how its ...

Scientists have created a new class of laser beam that appears to violate long-held laws of light physics. These new beams, which the team calls “spacetime wave packets,” follow different rules of ...

A U-rod in air transmits a laser beam like an optical fibre. When part of the rod is submerged in an index-matched mineral oil, the laser beam is no longer transmitted to the other end. Without ...
