Introduction Light exhibits both the properties of a wave and a particle. Its wave-like properties are best shown in its propagation while the particle-like properties in the emission and absorption of light.[1] As light behaves like a wave‚ superposition is observed between interacting waves. Superposition of waves is the addition of waves that travel across the same medium. The resulting wave from this addition has amplitude at a particular point that is the algebraic sum of the amplitudes of

photoelectric effect as well as the theory behind it. To determine h‚ multiple intensities of light were shined upon a cathode/anode apparatus and current and stopping potentials were measured. The weighted mean of the two values determined from different light intensities is (4.141 ± .008924) × 10-15 eV∙s‚ which is within .560σ of the world value of h. The independence of electron kinetic energy and incident light intensity is shown from the experiment. Also included is a brief analysis of the determined

and tedtalks talk about light behaves as waves and as particles‚ the idea that everything could be light in a concentrated state of motion strikes my curiosity‚ what is light? Defining light as the some of its part doesn’t answer the question.”RESISTANCE” light is resistance‚ the filament resist the current flowing from the positive‚ it’s day when the earth resist the light from the sun‚ thus the definition of light is abstract. when “FlOW” is being block it generates light‚ energy then is “FlOW”

before the theory of electromagnetism was developed‚ optical phenomena were studied‚ characterized‚ and used as probes of nature. Since the invention of the laser a half-century ago‚ this tool has become the preeminent source for all studies involving light. It too has revolutionized countless areas of high technology including telecommunications‚ data storage‚ semiconductor manufacturing‚ healthcare technology‚

each metal ion emits a different color of light‚ which corresponds to a certain wavelength of light‚ the presence of some elements may over power the flame and cause only certain wavelengths to be seen. For example‚ if sodium is present‚ it will overpower the other elements in the mixture‚ as the colors/wavelengths that they emit will not be visible with the yellow color from sodium. Also‚ it is very hard to tell which exactly which wavelengths of light are present if colors are blended. List

Heart of Darkness Essay Light and dark imagery is one element most commonly used in literature‚ and has held specific symbolic meanings for hundreds of years. Simply stated‚ light generally symbolizes good‚ while darkness symbolizes the complete opposite‚ evil. More specifically‚ Conrad uses detailed imagery of light and dark to show that white men can in fact be more savage than the natives. While the contrast of light and dark‚ white and black‚ and good and evil is a common theme in his novel

everyday products. For example‚ the light omitted by fireflies‚ deep sea fish and glow sticks is a result of this process. Luminol was synthesized from 3-nitrophthalic acid and then combined with potassium hexacyanoferrate(III) and hydrogen peroxide to omit a blue light. The product of this reaction is very unstable and is made by losing nitrogen and the electrons go from an excited state to ground state and the energy is emitted as a photon creating the blue light. After synthesizing the luminol‚ the

City Lights Movie Reflection A film in pantomime‚ I believe‚ means a romantic comedy where actors express their feelings by miming. The film’s story was mainly told through mime actions and the actors along with their facial expressions since it’s the only thing that is going on in a silent film‚ besides the sound. A pantomime uses its technique‚ in where a story is told using just music‚ sounds‚ and the motion and facial expressions. The scene I find memorable is where the main character firsts

Sudden Light di Dante Gabriel Rossetti I have been here before‚ But when or how I cannot tell: I know the grass beyond the door‚ The sweet keen smell‚ The sighing sound‚ the lights around the shore. You have been mine before‚-- How long ago I may not know: But just when at that swallow’s soar Your neck turn’d so‚ Some veil did fall‚--I knew it all of yore. Has this been thus before? And shall not thus time’s eddying flight Still with our lives our love restore In death’s despite
