Water refraction is the bending of light when it crosses the boundary between air and water. It happens because light travels at different speeds in different media and changes direction according to the refractive index.
The ratio of the velocity of light in a vacuum to its velocity in a specified medium. #negiup #negiup_original #light #refractiveindex #optics #physics (at Negiup ProductIons) https://www.instagram.com/p/B8xf-iHHlvT/?igshid=ostovz3kh4qh
💜 So how do we peek inside at the interior of a faceted stone? Watch carefully when the water pours over the stones...putting them in water effectively makes the facets disappear, revealing the stones' interior features and color zones! 😱 But why does this work? The answer lies in the purpose of faceting, and the way light beams travel through mediums other than air. See next post for the breakdown of this unique trick of the trade! 💜 #physics #lightbeam #refraction #angleofrefraction #refractiveindex

Researchers at Harvard University announced recently that they had successfully developed a means of manipulating light at the nanoscale, which could lead to photonic-based (rather than electronic) telecommunications. Think, ubiquitous fiber optics…
