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

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

As the source of light beam was getting farther away from the slit‚ the beam becomes narrower and shorter in addition to fading. This is because light particles escape more when they travel to go through the slit. B. Law of reflection Angle of incidence is the angle formed by a ray incident on a surface

Devices and Practices for Sensory Impairments Many students with physical disabilities and other health impairments may achieve more success if they are properly supported by an assistive technology (AT) device and AT support services. The two devices I chose were the cochlear implants for the deaf children and screen headers for the blind children. The cochlear implant is a small complex electronic device that can help provide a sense of sound. The students that will benefit from the cochlear

Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration‚ or converted into starch and stored. Oxygen is produced as a by-product. This process is called photosynthesis. Temperature‚ carbon dioxide concentration and light intensity are factors that can limit the rate of photosynthesis. Plants also need mineral ions‚ including nitrate and magnesium‚ for healthy growth. They

kinds of artificial light sources for photography Light‚ is the main ingredient in a photograph. There are of course other ingredients: time‚ composition‚ subject matter‚ emotion and your unique style‚ but light is the thing that makes photography work. Light is the thing that early inventors had to hold or fix‚ in order to make a photograph stick around. We call nature’s light‚ natural or available. Think of sunlight or moonlight. There are four common types of artificial light sources used in photography

Green Technologies Green technology‚ also known as environmental or clean technology‚ minimizes impacts on the environment and natural resources. It’s based on concepts such as conserving water and energy‚ reducing waste and pollution‚ harnessing renewable energy sources‚ finding ways to reuse materials‚ and developing less polluting technologies. Green technology is everywhere these days; in the news‚ politics‚ fashion‚ and of course technology. Green Technology is becoming so widespread
