Light is just one portion of the various electromagnetic waves flying through space. The electromagnetic spectrum covers an extremely broad range‚ from radio waves with wavelengths of a meter or more‚ down to x-rays with wavelengths of less than a billionth of a meter. Optical radiation lies between radio waves and x-rays on the spectrum‚ exhibiting a unique mix of ray‚ wave‚ and quantum properties. At x-ray and shorter wavelengths‚ electromagnetic radiation tends to be quite particle like

Of course‚ we live in an imperfect world and not all surfaces are smooth. When light strikes a rough surface‚ incoming light rays reflect at all sorts of angles because the surface is uneven. This scattering occurs in many of the objects we encounter every day. The surface of paper is a good example. You can see just how rough it is if you peer at it under a microscope. When light hits paper‚ the waves are reflected in all directions. This is what makes paper so incredibly useful -- you can read

emergency vehicles. Red color is being chosen as the color for the emergency vehicles strobe lights is because of the night vision capability by using this color. It cannot be denied that red color is more easily to be notice if compared to other color. Red color can catch more attention and alert when we saw red because red is signal us about danger. Advantages and Disadvantages White: light is the most effective attention-getting signal‚ containing all visible spectral wavelengths

career.... “manufacture of his lamp and furniture designs.” This book is for architects who are truly interested in how people feel in their buildings. Bill Lam gives a clear explanation of the properties of light‚ particularly sunlight‚ and provides an understandable guide to designing with light to create more livable architectural environments. Sunlighting as Formgiver for Architecture The very begining of the book says about the importance of the sun‚ that “throughout the history‚ throughout

Light From personal experience I would say light within architecture is what makes you feel uplifted as you walk into a room or a space. Light can be controlled and manipulated within certain spaces by adding light or having an absence of light. Light can completely change the dynamics of a room or space and can also have a very strong effect on the mood. Light within architecture can either be natural or synthetic‚ both creating a special experience within a room. In my research I will

The absence of light There is no darkness‚ only the absence of light. You cannot measure the dark; it is a measure of illumination‚ or in some cases‚ a lack of it. This point stands in both a physical and metaphorical state. Imagine a pitch-black room‚ if I were to ask you “what do you see?” would you say “the dark”? How can you see darkness? You can’t. You notice that there is an absence of light. In the same way‚ when we judge someone to be‚ in essence‚ evil‚ that is just how we perceive it

Conclusion: Explain‚ in your own words‚ why different elements produce different colors of light when heated. Each element has a unique electron configuration. When heated‚ the electrons are energized and this leads to a higher quantum state. The color depends on the distance you have and the original electron configuration. Why do you think elements must be heated before they emit colored light?The light color is the electronic transitions between orbitals. When an electron drops to a

Light Emission and Absorption - Active Reading When atoms absorb energy‚ electrons can jump to higher energy orbitals. When the electrons move back to their original configurations‚ that energy is given off as light! Travel to the website linked below and take Cornell notes for each section.

LIGHT EMITTING DIODES Light Emitting Diodes are electronic components that use the flow of electrons to excite materials into emitting photons of light. A diode is a basic electronic component that allows electricity to flow one way only. The discovery of "light emitting" diodes we believe was an accident sometime around 1907 when a diode in an early radio transmitter was noticed to glow when in use. Incandescent bulbs use resistance in a filament to impede the flow of electricity‚ heating
