Where Are the Light Switches? Essay

when I relized something. Why would I sleep in my own house after what just happened? Well where eles could i go? I wonderd. I got out of bed and picked up the box. I decided that I would not be very safe here at my home and decided to take it somewhere. I looked around outside then walked to my car. I than put the package in the seat next to me. I figured that it would be safer with me then at my house where it could be stolen. I also figured that scince it was only 5 pm that I could get some coffee…

devices i.e Switches and Hubs. Various performance metrics like throughput, collision count, traffic received, traffic sent and delay are analysed by implementing the network with and without switches. The network is then modified such that its maximum performance and efficiency is achieved. OBJECTIVE The main objective of this lab is to design a network with and without switches and examine the network’s parameters in both the scenarios. Two such scenarios were created: 1) Only hub (where one hub is…

investigate whether light intensity of incoherent lights varies inversely with the square of the distance holds true in real-life situations and under laboratory conditions. Techniques utilised in the experiment included measuring the distance from the light source to the light sensor, recording the light intensity of a light source and recording observations with accuracy. The light from the light source that passes through the cardboard cylinder tube changes as the distance from the light sensor increases…

Light bulbs are an invention that transformed the modern world to what we know it to be today. It was first created by Thomas Edison after countless hours of trial and error. He finally found a combination that worked and lasted for twelve hundred hours. It relied on a bamboo filament and was more efficient after Edison was able to remove more oxygen from the bulb. There are now four main types of light bulbs: incandescent, halogens, fluorescent, and LEDs. Although performing one basic task they…

“Technology in Education; Where it has been, Where it is now, and Where it is Going” “Before you become too entranced with gorgeous gadgets and mesmerizing video displays, let me remind you that information is not knowledge, knowledge is not wisdom, and wisdom is not foresight. Each grows out of the other. And we need them all” (Re-inventing 1995). These words spoken by the distinguished author, Arthur C. Clarke, bring to light where exactly the technological situation in education is and the…

Thin. Light. Flexible. So I assume many of you have heard of LED screens or panels, chances are you are probably reading this on one of them. Or if you’re one of those people who still use that stuff called paper then maybe on that. Well whatever you are reading this on prepare to empty you’re wallet’s because this new technology will surly brighten your day! LED’s or Light Emitting Diodes have been around since the 60’s and I think they are starting to decline. The new technology slowly replacing…

Solar energy technologies include solar heating, solar photovoltaics, solar thermal electricity and solar architecture, which can make…

science of light, astronomers use factors such as wavelengths to interpret stars’ temperature, heat, distance, size, mass, density, etc. To obtain all of this information certain light gathering instruments must be used. These instruments include telescopes. To record this information spectrographs are also mainly used to record the spectrum and dispersion of light. In light there are different waves and particles. Light is made up of electric and magnetic fields. Due to this fact, light is an example…

Light and Geometric Optics. That is the title for Unit D. Unit D deals with the electromagnetic spectrum, Ray models of light, Refraction, and a lot of other topics. Light is used in many different ways. Mirrors and televisions use light so you can see yourself and the show you are watching. The light bulbs we utilize use different sources of light for power. We have advance and have been able to find many uses for many different things that give us light. But first we must know how light…

Automatic Street Light Control System is a simple and powerful concept, which uses transistor as a switch to switch ON and OFF the street light automatically. By using this system manual works are removed. It automatically switches ON lights when the sunlight goes below the visible region of our eyes. It automatically switches OFF lights under illumination by sunlight. This is done by a sensor called Light Dependant Resistor (LDR) which senses the light actually like our eyes.…
