When it comes to light, certain types of fabricated materials behave in a radically different manner from ordinary materials like water and glass: they have negative refractive indices, so that light ...

The film explores the properties of light, including reflection and refraction, through various experiments. It demonstrates how light travels in straight lines, how mirrors can reflect images, and ...

Explains the concept of light traveling in straight lines and demonstrates this through various experiments. It shows how light can be observed through holes in cards, how it behaves in a lightproof ...

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 ...
