The Discovery Center Museum is offering an engaging experiment to help children understand the science of light refraction and color mixing using simple materials such as a box, water bottles ...

Sometimes when you look into a swimming pool it’s difficult to tell how deep the water actually is. If you grab something long, like a stick, you can use it to test the depth of the water. Upon ...

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 ...

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 ...

Understanding diffraction and dispersion is key to optical science, influencing technologies like spectroscopy, fiber optics, ...

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 ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. This article is more than 4 years old. Light is well known to exhibit ...

Created more than 400 years ago, the telescope is a tool that has allowed both amateurs and scientists alike to explore the sky in much more detail than they ever could with their naked eyes. All ...
