THE author pointed out that most previous experimenters, A especially Rood, had measured the amount of the transmitted light, and that any percentage of error in this ...

Vol. 86, No. 3, Papers on Astronomy, Botany, Geology, Paleontology, and Zoology (Jul. 8, 1943), pp. 351-363 (13 pages) In the first part of the present paper the amount of total light reflected by ...

Discover the science behind seeing your reflection in water. Light travels in straight lines and bounces off smooth surfaces, ...

If you shine a light at a mirror, the beam is reflected inward to a central focal point, bouncing back toward you in a predictable manner—it’s a simple reflection of light, a spatial inversion. When a ...

A research team has developed a new way to measure and predict how plant leaves scatter and reflect light, revealing that ...

Researchers demonstrate a new technique for suppressing back reflections of light, leading to better signal quality for sensing and information technology. Researchers demonstrate a new technique for ...

In about a year, a new NASA instrument designed and built in Colorado will ride on the International Space Station (ISS). From there, it will look down at Earth to measure the light reflecting off our ...

Mirrors help you see objects outside of your line of sight, whether it’s a car passing you on the highway or an unfortunate rash on your face. And as it turns out, with some extra computer processing, ...

Bigger! Brighter! Nearly 110 percent light transmission! Sees in the dark! Few things in hunting optics are more hyped and misunderstood than riflescope brightness. Every shooter wants a bright, ...

Brightfield microscopy has been widely used for hundreds of years, while reflection contrast microscopy is relatively new technology. As one of the earliest and simplest microscopy techniques, ...
