polaroid filters are used and placed so that one is rotated 90 degrees to the other‚ no light will be able to pass. Some polarization will also occur during reflection‚ refraction‚ and scattering of light. When reflecting off non-metallic surfaces‚ the resulting light will be polarized parallel to the reflected surface. During refraction‚ a beam of light will be split up into two polarized beams‚ one polarized parallel and one perpendicular to the boundary. Scattering also causes partial polarization

Light that is visible to the human eye is a small portion of the electromagnetic spectrum which can vary in colour based on the wavelength of what is being seen at any particular time. This visible light has a primary function of causing electrons to become more active with higher energy rates. The colour that is seen revolves around the size of this portion which is noted as the wavelength. White light is a culmination of all colours which is the cause of it being the brightest. Furthermore‚ when

is an end member of this series. The plagioclase series comprises felspars that range in chemical composition from pure NaAlSi3 O8 to pure CaAl2 Si2 O8 . The various plagioclase feldspars are identified from each other by gradations in index of refraction and density in the absence of chemical analysis and/or optical measurements. Albite is also an end member of the alkali or K-feldspars whose series ranges from pure NaAlSi3 O8 to pure KAlSi3 O8. This series only exists at high temperatures with

"Discourse on Method". In addition to this‚ Descartes had numerous explanations of the physical world. His most prominent explanations are the first modern formulation of laws of nature‚ theory of planetary motion‚ and the study of reflection and refraction of light. Above all things‚ Rene Descartes was a philosopher. Often referred to as the "Father of Modern Philosophy"‚ Descartes contributions to philosophy are some of the

Earth’s rotation. The time of sunset is defined in astronomy as the moment when the trailing edge of the Sun’s disk disappears below the horizon. The ray path of light from the setting Sun is highly distorted near the horizon because of atmospheric refraction‚ making the sunset appear to occur when the Sun’s disk is already about one diameter below the horizon. Sunset is distinct from dusk‚ which is the time at which the sky becomes completely dark‚ which occurs when the Sun is approximately eighteen

PATHOLOGY CASE REPORT XL dominant Alport Syndrome: a rare condition and a rare mode of genetic transmission INTRODUCTION Alport syndrome (AS) is a rare abnormality of glomerular basement membrane caused by mutations in several different genes‚ all of which encode particular forms of type IV collagen‚ a major component of basement membrane. It is characterized by chronic renal failure leading to end-stage renal disease (ESRD) and is often associated with sensorineural deafness (Kanski 2003)
