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 ...

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 ...

The film demonstrates the principles of optics, particularly how light behaves and interacts with objects. It explains that light travels in straight lines, which is evident in the formation of sharp ...

THE experiments of Hill and Swallow 1 in August 1949 showed that the method of seismic refraction shooting at sea, which had been developed at Cambridge, was suitable for deep ocean work. Effort was ...

Scientists have ample evidence to prove the Earth is a sphere. But some social media users claim to have devised an experiment showing the earth is flat. The post shows a green laser beam projected ...
