A Brief History of Light ( by Efthymios Kallos) (edited by Mrs. John & Mr. Lefebvre) | The struggle to understand light | The main issue of the early theories of light was to resolve whether it was a wave or a particle‚ and this proved to be a difficult task. It started as a particle from the ancient Greeks‚ then it became a wave with Huygens‚ then Newton suggested a particle theory again‚ then Fresnel and others suggested a wave theory again‚ then Einstein suggested a particle theory once

NAME : ……………………………………………….. GROUP :………………………………………………... TUTORIAL 2 (ALPH20) WAVES WAVES BEHAVIOR 1. To demonstrate interference of light waves‚ Thomas Young allowed light from an illuminated single slit to fall on a pair of narrow closely-spaced slits. Explain: a. Why light from separate lamp bulbs can never produce an interference pattern? b. Why double slits used as above do give an interference pattern? How would the interference pattern differ

Some say there is nothing stronger than a bond between a father and his son. The trying and heartwarming relationship between the father and his son is shown in the story “Powder” by Tobias Wolff. There are many differences and similarities between the father and his son‚ maybe a few more differences than similarities but that doesn’t stop them from spending time with each other. To begin with‚ throughout the story the reader makes it clear the differences between the two characters. First off

“Powder” "Powder‚" by Tobias Wolff‚ is about a man recalling his memory of a specific ski trip taken with his father‚ at a time when his parent’s were on the verge of divorce. He recounts the day with vivid detail‚ telling us the reasons why his parents divorce was imminent‚ but also how much he loves his father despite his faults. The boy conveys his controlling behavior to the point of numbering his clothes to ensure rotation‚ and asking for school assignments well in advance so that he can

The history of powder coating What exactly is powder coating? Powder coating is the process of coating a surface in which a powder material is applied using an electrostatic or compressed air method. Then the applied powder is heated to its melting point‚ after it forms to a firm‚ durable finish the product is very resistant to scratches‚ cracking‚ peeling‚ UV rays‚ and rust. Powder coatings over the years have become the coating technology of choice for consumable goods from toolboxes

Running head: Research Paper: HOLOGRAMS 1 Yasmine Briedj Adelphi University What do flying cars‚ time machines and holograms all have in common? They’re future technologies that the world never thought they would see brought to life. This was until holograms were created. When talking about holograms‚ the first thing that usually comes to mind is their use in the entertainment industry for things like 3D movies and recreating musical artists. But‚ holograms actually have more uses

INTEFERENCE -is the phenomenon that occurs when two waves meet while traveling along the same medium. The interference of waves causes the medium to take on a shape that results from the net effect of the two individual waves upon the particles of the medium. To begin our exploration of wave interference‚ consider two pulses of the same amplitude traveling in different directions along the same medium. Let’s suppose that each displaced upward 1 unit at its crest and has the shape

Diffraction and interference describe effects unlike what geometrical optics would predict: the edges of shadows are not quite sharp; the beam passed by a slit is not a narrow rectangle. Diffraction patterns carry information about the spacing and location of the elements in the diffraction grating that produced them. Conversely‚ if we know the structure of the grating‚ we can deduce properties about the incident light‚ in particular its wavelength. This will be our task‚ in this first optics
