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 ...

Students use mirror equations to determine the position and type. Students use mirror equations to determine the position, type, and size of mirror images for curved mirrors mathematically. Optical ...

Based on highly accurate optical interferometry and fundamental quantum calculations, researchers in the US are developing an improved definition of the SI unit for pressure that will consign the ...

(Nanowerk News) This will potentially allow them to create more compact and efficient elements for lasers, sensors, and optical chips. Moreover, it proves the hypothesis that ITMO physicists had about ...

The Brix scale, derived from the refractive index of a solution at 20 degrees Celsius (68 Fahrenheit), is widely known. Originally, it was established by determining the weight percentage of sucrose ...
