Explores the principles of light, reflection, and magnification through hands-on experiments. Children observe how a magnifying glass focuses sunlight to create heat, examine the effects of light on ...

I test a series of light experiments to explore reflection, refraction, and optical illusions, demonstrating how light ...

A LIGHT wave, when reflected 1 at the surface of separation of two media, may be altered in amplitude, or wavelength, or phase. Whilst, however, a change of amplitude or wave-length produces an ...

Through the looking glass: Scientists at the City University of New York (CUNY) created a "mirror" that can reflect an electromagnetic wave backward in time. It is not the first time this has been ...
