contrasting views that light either consists of particles or waves. Light is a perplexing phenomenon puzzled by Ancient Greeks and scientists for years. Even Issac Newton developed incorrect theories on light‚ when he was the inventor and genius behind physics. It has been proved that light can be both a particle and a wave. Human eyes collect light that is reflected from a source. For example‚ the light from a pencil comes from the source of light in the sun and travels to the pencil to bounce up to the

Telescopes A telescope is an instrument that aids in the observation of remote objects by collecting electromagnetic radiation such as visible light. The first known practical telescopes were invented in the Netherlands at the beginning of the 17th century‚ using glass lenses. They found use in terrestrial applications and astronomy. Telescopes come in all shapes and sizes‚ from a little plastic tube you buy at a toy store for $2‚ to the the Hubble telescope which weighs several tons. Amateur telescopes

distinguished scientist who viewed the world from a different perspective and he played an invaluable role developing many of the sciences of the contemporary world. He focused his entire career studying complicated topics such as math‚ alchemy‚ optics‚ and physics. After centuries of studying his life and work‚ some even speculate that Newton was searching for a series of principles that he believed to define the universe (Aughton 136). While he may have never found the set of principles that he believed

HISTORY OF FIBER OPTICS * In 1840‚ Daniel Colladon and Jacques Babinet demonstrated the principle of guiding light by refraction. * It was followed by a public demonstration by John Tyndal in 1852. In 1870‚ Tyndal wrote about the property of total internal reflection in his book about the nature of light. * In 1880‚ Alexander Graham Bell and Sumner Tainter invented the Photophone‚ a device capable of transmitting sound waves over beam of light. This is considered as mankind’s first attempt

An Innovative Polariscope for Photoelastic Stress Analysis Jon R. Lesniak 1‚ Michael J. Zickel1 ‚ Christopher S. Welch2‚ Deonna F. Johnson2 Abstract An innovative polariscope involving a single rotating optical element and a digital camera for full-field image acquisition allows automated data to be acquired quickly and efficiently. Software analysis presents the data in an easy to interpret image format depicting the magnitude of the shear strains and the directions of the principal strains

movement of the planets and other celestial bodies‚ and their orbit around the sun. (The Physics Classroom) Since the sun has the greatest amount of mass in the solar system‚ all of the other objects and planets in the solar system are pulled towards it. In 1666‚ Newton laid down the foundations of his three laws of motion. These laws of motion are used in everyday life and laid the groundwork for future physics developments. His first law may be given thus: “A body remains at rest or‚ if already in

this experiment‚ we examine the interference and diffraction phenomena of light‚ both of which can be described by the wave theory of light. While interference is just the superposition of waves‚ diffraction is also any deviation from geometrical optics that results from the obstruction of a wavefront of light. In other words‚ diffraction is considering the double-slit experiment by taking into account the width of the slit openings‚ too. Another way of distinguishing between interference and diffraction

Principia Mathematica Philosophiae and his ideas about gravity and the invention of the telescope. Isaac Newton was born on January 4‚ 1643 and his first contribution to the enlightenment was making the telescope. In 1668 he created the telescope for optics and this invention proved the idea of color and light. He proved that light was the composite of all other colors and that light is made up of particles. A little bit later a scientists named Robert Hooke came into play. Him and Newton did not
