Extractions: Photo Gallery Silicon Zoo Pharmaceuticals Chip Shots ... Movie Gallery When electromagnetic radiation, in the form of visible light, travels from one substance or medium into another, the light waves may undergo a phenomenon known as refraction , which is manifested by a bending or change in direction of the light. Refraction occurs as light passes from one medium to another only when there is a difference in the index of refraction between the two materials. The effects of refraction are responsible for a variety of familiar phenomena, such as the apparent bending of an object that is partially submerged in water and the mirages observed on a dry, sandy desert. The refraction of visible light is also an important characteristic of lenses that enables them to focus a beam of light onto a single point. Introduction to the Refraction of Light - As light passes from one substance into another, it will travel straight through with no change of direction when crossing the boundary between the two substances head-on (perpendicular, or a 90-degree angle of incidence). However, if the light impacts the boundary at any other angle it will be bent or refracted, with the degree of refraction increasing as the beam is progressively inclined at a greater angle with respect to the boundary. As an example, a beam of light striking water vertically will not be refracted, but if the beam enters the water at a slight angle it will be refracted to a very small degree. If the angle of the beam is increased even further, the light will refract with increasing proportion to the entry angle. Early scientists realized that the ratio between the angle at which the light crosses the media interface and the angle produced after refraction is a very precise characteristic of the material producing the refraction effect.

Extractions: Famous Physicists Physics is more than just about concepts and theories, it is more than protons, electrons, energy and motion. Physics is about our attempts to understand the natural phenomena of our universe. In studying physics we are studying theories constructed by physicists; therefore, we should also strive to understand these famous physicists, as well as the era and environment which influenced their theories. For example, during the middle of the 1900's World War II influenced nuclear physics, and during the second half of the 1900's telecommunications influenced solid state physics. To better understand physics and the key people behind the theories, high school students have developed an inventory of biographies of physicists.

Em 1613, sucedeu o pai nessa função. Quatro anos maìs tarde, criou um método para determinar distâncias por meio de triangulação trigonométrica. Esse método é utilizado até hoje para executar mapeamentos topográficos. (É a base, inclusive, para os efetuados com auxílio de satélites.) No campo da Optica, Snell analisou o desvio que um raio de luz sofre ao passar obliquamente de um meio menos denso a outro mais denso (por exemplo, do ar para a água). Desde o século I já se sabia que esses dois ângulos diferentes, formados entre o raio e a perpendicular à fronteira entre os meios, guardavam entre si uma proporcionalidade que se mantinha mesmo quando a posição da fonte de luz era alterada. Snell refinou essas observações e, através de medidas mais acuradas, descobriu haver uma relação constante entre os senos desses ângulos. Tal conclusão só seria publicada doze anos após sua morte por Descartes, o qual, no entanto, não citou seu autor.

Extractions: An astronomer and mathematician best known for his law of refraction of light. In 1613 he succeeded his father Rudolph Snell (1546-1613) as professor of mathematics at the University of Leiden. He studied the loxodrome the path on the sphere that makes constant angle with the meridians. In 1617 he published Eratosthenes Batavus , which contains his methods for measuring the earth. He also improved the classical method of calculating approximate values of by polygons. Using his method 96 sided polygons give correct to 7 places while the classical method yields only 2 places. van Ceulen 's 35 places could be found with polygons of 2^30 sides rather than 2^62. Although he discovered the law of refraction, a basis of modern geometric optics, in 1621, he did not publish it and only in 1703 did it become known when Huygens published Snell's result in Dioptrica Sommerfeld , Arnold Johannes Wilhelm
