Abstract: A star tracker operating inside the atmosphere requires stellar atmospheric refraction (SAR) correction with rapidness, autonomy, and accuracy to promote its attitude determination. To meet ...

Abstract: Owing to the effects of atmospheric refraction, the path of light propagation is bent, making the three-point collinear principle inapplicable and influencing the geometric accuracy of ...

Refraction is the change in the direction of light due to a change in its speed as it enters a different medium. While the speed of light is constant in a vacuum, it decreases in denser materials, ...

Got a space-obsessed kiddo? Or maybe you’ve got a solar system project due tomorrow and no idea where to start? Either way, these Free Solar System Worksheets (PDF) are here to save the day (and maybe ...

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 ...

Refractive errors are common eye issues that can cause blurry or distorted vision. Treatment usually involves wearing glasses or contact lenses or getting procedures ...

If you’ve gathered five Memory Vestige: Light from the enemies you encounter in the Cysts, there’s a good chance you’ve got Memory: Refractions of Light marked on your map. And while the location of ...

Snell's Law relates the sines of the angles of incidence and transmission to the refractive indices of each medium at the boundary. It applies to all materials across all phases of matter, with angles ...

This disappearing spider trick is a simple Halloween science activity and a great refraction demonstration. Children can watch as a drawing of a spider disappears when water is poured into a glass ...

Light Refraction, it might sound like a big scary term, but today’s experiment is basically about rainbows! Who doesn’t love a rainbow experiment? These simple experiments are perfect for your ...
