scientists have recently found that they‚ along with other ordered non-periodic structures‚ exhibit unique optical effects as well‚ specifically negative refraction. To understand how ordered non-periodic structures are tested in the field of optics‚ one must first understand photonic crystals: crystals which exhibit effects of photon-directing similar to the electron-directing effects of semi-conductor crystals. The resulting phenomena occur by the fact that photonic crystals have dielectric

still being littered with ribs of broken ships whose captains couldn’t see the shore line. In 1822 Augustin Fresnel‚ a French physicist and engineer invented a lens that would change light houses everywhere. Fresnel contributed to the theory of wave optics and studied the behavior of light both theoretically and experimentally. Fresnel worked on numerous formulas to calculate the way light changed directions‚ while passing through the prisms. He worked with some of the most advanced glass makers of

An electron microscope is a type of microscope that produces an electronically-magnified image of a specimen for detailed observation. The electron microscope (EM) uses a particle beam of electrons to illuminate the specimen and create a magnified image of it. The microscope has a greater resolving power than a light-powered optical microscope‚ because it uses electrons that have wavelengths about 100‚000 times shorter than visible light (photons)‚ and can achieve magnifications of up to 1‚000‚000x

microscopes can be used to view things such as biological tissues and organisms. Also‚ another popular microscope used in human biology is the stereo microscope‚ which is commonly used to dissect and examine human tissue. Discussion When studying the “optics” slide in the interactive section of this lab it displayed image orientation. To display this it took the letter “e” and showed you the standard view to the naked eye and then it showed you the view through a light microscope and it looked very different

Fundamental of Islamic Ornament in Geometrical Art Abstract Islamic ornament is underlying the pictorial or an icon. It ’s inspirational is from nature like stars‚ moon‚ trees and etc. Islam stricly does not allow arts in form of living things such as human and animal. In order to inhibit worshipping idol other than worshipping Allah subahanahuwataala. Basically the art of Islam can define as merge of science and mathematics learnings. In this content we will be more focing on geometry

Polarized light are those that are vibrating in one direction- in a single plane such as up and down. Those that are vibrating in more than one direction -- in more than one plane such as both up/down and left/right -- are called unpolarized light. Generally‚ unpolarized light can be considered to be vibrating in a vertical and a horizontal plane. To polarize light‚ one can transmit the light through a polariod filter which will only allow light of single polarity to pass. The resulting light will
