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 ...
Introduction If you pour water into a clear glass, what color is it? It's clear, right? But what happens if you try to look through it to see the world on the other side of the glass? It looks a ...
Father and son, Dr. Walter Placek, Wilkes University professor, and David Placek, a teacher in the Wyoming Valley West School District, conducted science experiments on light and prisms with the third ...
Recent experiments that demonstrate the negative refraction of light could bring a heated scientific debate to a close, and give negative-index materials a positive future Figure 1: Negative-index ...
Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...
Twenty-odd years before Newton stated the three laws of motion, he conducted a simple, breakthrough prism experiment. He poked a hole through his window shade, allowing a single beam of light to shine ...
When people look into a mirror, they see an image of themselves behind the glass. That image results from light rays encountering the shiny surface and bouncing back, or reflecting, providing a ...
PITTSBURGH (KDKA) -- Without light, we can't have sight. We see objects because of how light interacts with those objects, our eyes pick up that light, and our brains interpret it. This seems rather ...
If beauty is in the eye of the beholder, it’s fair to say the general public has rendered science plain. The accumulation of data in controlled situations isn’t, after all, loveliness embodied. But an ...
