Dispersion Of White Light by a Glass Prism: When a beam of white light is passed through a glass prism‚ it is split up into a band of colours called spectrum. This is called dispersion of white light. The spectrum of white has the colours violet‚ indigo‚ blue‚ green‚ yellow‚ orange and red (VIBGYOR). The red light bends the least and the violet light bends the most. A rainbow is a natural spectrum appearing in the sky after a rain shower. It is caused by the dispersion of sunlight by water

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

My life is like Wendy Cope’s poem‚ Some More Light Verse. In the beginning‚ it tells the reader that sometimes an individual will feel symptoms of depression when they attempt to achieve some far-reaching ambitions‚ but ultimately they cannot stop trying. They must be steadfast‚ or else they won’t leave‚ grow or progress from their current status‚ lifestyle or position. That is the aphorism I live by. With regards to this doctrine‚ Wendy Cope has also declared “In my case‚ the long gaps between my

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

LED LIGHTS A Museum Exhibit Case Study By Kathy Andal September 6‚ 2013 In April 2014‚ the Durango County Museum of History installed a small exhibit titled Our heritage: Pictures from the past. The collection consists of five daguerreotypes and several silver albumen prints. A study was made to measure the benefits and costs of using LED. lights instead of traditional halogen lamps.

Throughout the history of the human civilization‚ historians have been able to develop labels for the different historical ages by the important events which occurred within each of them. For example‚ the Dark Ages is a reference to the historical period within Europe in which there was a deterioration of the economic and social life. The deterioration was partly due to the degeneration of the Roman Empire. Each age can be labeled by the protruding theme which identifies the way which life was for

Silverstein PHY 101 Section 10497 March 4‚ 2013 Light up this World Purpose: In this lab experiment‚ LED lights will be used to show how when E&M radiation is absorbed‚ the energy is converted to heat. A drop of isopropyl alcohol will absorb light energy of different colors‚ and the evaporation rate of the alcohol will be measured. The key to this lab is the evaporation rate is directly related to the energy of the light shining on the drop. Materials: * * LEDs and circuits
Premium Electromagnetic radiation Light Wavelength
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

energy?”. In this era‚ the earth population growth but the natural resources faced crisis with limited resources to fulfill the high demand of the population. Non-renewable energy is finite resources which is dwindling because of high cost and damage our environmental. Every day we consume energy from a wide of sources. Therefore‚ the need for cheap and obtainable resources is greatly needed. The replace of non-renewable energy with energy from renewable sources has many benefits. Renewable energy

Brazil‚ to light his workshop when his neighbourhood was suffering energy shortages‚ enabling him to continue working. His neighbours‚ intrigued by the idea‚ soon started following suit‚ adding the bulbs to their homes in kitchens‚ bathrooms and living areas where electric light was prohibitively expensive and inefficient. The bottle bulb revolution was then further enhanced by The “MyShelter Foundation”‚ which runs a program in the Philippines called “Isang Litrong Liwanag: a Liter of Light”. Based
