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 ...

The double-slit experiment is one of the most famous experiments in physics and definitely one of the weirdest. It demonstrates that matter and energy (such as light) can exhibit both wave and ...

The famous double-slit experiment, which demonstrated that light is both a wave and a particle, has been performed using “slits in time”. The techniques involved present a new way to manipulate light ...

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

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew.

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 ...
