1. The reflection of light from the surfaces of many kinds of leaves has been measured by means of a direct reading spectrophotometer, the measurements being made normal (that is, at an angle of 90⚬ ...

Transparent plastic optical lenses can be manufactured cheaply and in any shape. However, a downside is that they reflect light just as much as glass does. Researchers are exhibiting a new type of ...

LIGHT, which in everyday experience travels in straight beams, has been trapped on complex curved surfaces. The feat is not just a parlour trick – it could help people visualise how light travels in ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 119, No. 12 (March 22, 2022), pp. 1-9 (9 pages) Light propagation on a two-dimensional curved surface embedded in ...

Researchers at the INM -- Leibniz Institute for New Materials have now developed a new method that enables electroluminescence on large, curved surfaces in a cost-effective way: in this case, the ...

A LIGHT wave, when reflected 1 at the surface of separation of two media, may be altered in amplitude, or wavelength, or phase. Whilst, however, a change of amplitude or wave-length produces an ...

Scientists have created new types of 2D nanostructured surfaces which appear as realistic 3D objects – including shading and shadows – using nano-engineering techniques. When light hits an object, the ...

(Nanowerk News) Transparent plastic optical lenses can be manufactured cheaply and in any shape. However, a downside is that they reflect light just as much as glass does. At the K trade fair in ...
