A spherical mirror is that mirror whose reflecting surface is the part of a hollow sphere of glass. Spherical mirrors are of two types: concave mirror and convex mirror. In a concave mirror reflection ...

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⚬ ...

Light collection efficiency is an important factor that affects the performance of many optical and optoelectronic devices. In these devices, the high reflectivity of interfaces can hinder efficient ...

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 ...

(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 ...
