the speed of light “So far as problems involving light are concerned‚ the electrons (in atoms) behave as though they were held by springs”.Feynman “In a microscopic but otherwise classical analysis‚ the electric field in electromagnetic radiation accelerates electrons held by springs in the atoms of a piece of glass‚ and these accelerated electrons re-radiate in all directions. The observed light is the superposition of the electric (and magnetic) fields of the incoming light and the re-radiation

cannot imagine life without it is the light bulb. Thomas Alva Edison invented the light bulb in the year 1879. With the advancement in technology‚ today we have different types of light bulbs such as Incandescent‚ Halogen‚ Fluorescent‚ Compact Fluorescent Lamps‚ High-Intensity Discharge Lamps‚ Low-Pressure Sodium Lamps‚ LED (Light Emitting Diodes). The most common light bulbs that are generally used for household purposes are compact fluorescent and incandescent light bulbs. Incandescent lighting is

In optics‚ corpuscular theory of light‚ originally set forward by Pierre Gassendi‚ states that light is made up of small discrete particles called "corpuscles" (little particles) which travel in a straight line with a finite velocity and possess kinetic energy. It was largely developed by Sir Isaac Newton. Newton’s theory remained in force for more than 100 years and took precedence overHuygens’ wave front theory‚ partly because of Newton’s great prestige. However when the corpuscular theory failed

Lady Macbeth’s opening words introduce a new level of emotional intensity. Fear of failure has been replaced with fear of discovery‚ and even though she describes herself as drunk with boldness and on fire with passion‚ she is just as easily alarmed as her husband is by the tiniest noises and movements. Her swift changes of thought and speech foreshadow the language of her final lapse into madness in the sleepwalking scene (Act V‚ Scene 1)‚ when she relives these same moments. Yet‚ despite all

Lights‚ Camera‚ History Book Review Lights‚ Camera‚ History takes the reader through history within the film. A large problem this book faces is the depiction of history within films and the challenges directors face. This book provides an enthusiastic argument in the defense of directors saying the purpose is to make money not be historians. It is important to tell students do not accept what you see as fact. In the chapter “In Praise of the Biopic‚” the author talks about: “Reds‚ They Died with

What is the Effect of the Colour of Light on the Rate of Photosynthesis? By Amelia Rowan‚ 12SDa Aim To discover whether the colour of the light source has any effect on the rate of photosynthesis of a sample of algae. Hypothesis It was predicted that the colour of the light source would have a very slight effect on the rate of photosynthesis. It was further predicted that when the sample was placed under the green light‚ the rate of photosynthesis would be the lowest. This hypothesis was arrived

neon lights: -consists of brightly glowing electrified glass tubes or bulbs that contain rarefied neon or other gases History: -Neon (the element) was discovered in 1898 by William Ramsay and Morris W. Travers. After they had discovered neon‚ they had explored neon’s many properties using an electrical gas discharge tubes. They later wrote that “the blaze of crimson light from the tube told its own story and was a sight to dwell upon and never forget.” -following neon’s discovery‚ neon tubes

Light Effects Refraction‚ reflection and dispersion are all processes which happen when a ray of light is shone at either a glass block‚ a mirror or a prism. The ray box is the light source. Mirror When the ray box is shone at a mirror the angle of incidence is always a few degrees different to the angle of reflection. For example‚ if you shine a light ray into a mirror at 60* then it will reflect out at about 57*. Glass Block If I shine a light ray into a glass block then the light would
