What Is The Importance Of Electric Light

A form of electromagnetic radiation of a wavelength, which human eyes have the ability of detecting is known as light. Light is a form of energy, that stimulates sight and makes objects visible. Light, mostly electrical light, plays an extremely important role in today’s modern society, as it is an important form of energy that allows humans to live the convenient life they currently live. One of the obvious uses of light energy in one’s daily life is to provide light, allowing one to see their surroundings and avoid living and working in the dark. Electric light is the most used form of artificial light, and is found to be used in almost everything, from providing interior lighting for building and houses, to providing exterior light for nighttime

As artificial lights are created through the conversion of electrical energy, they are easily accessible in developed countries, as their governments would be able to provide sufficient amount of electricity legally. In addition, most people would also be able to afford the electricity being provided. However in poverty-stricken developing countries, this is unfortunately not the case. For example in the developing provinces of the Philippines, most citizens live in poverty, with each citizen of those provinces earning a salary of US $2 a day. At this rate of income, these poor citizens would not be able to invest in artificial lighting, as they would barely be able to purchase their essential

In addition, the electricity does not reach the poor provinces of this country, and even though there are illegal connections, due to poverty the citizens cannot afford to invest in it. To help reduce this issue, Alfredo Moser invented Solar light bottles. Solar light bottles are a cheap and efficient way of providing light naturally through the use of materials that are easily accessible and through the use of sunlight. To create the solar light bottles, first find a one liter plastic bottle. Then, fill it with water mixed with bleach or chlorine. The bleach and chlorine will prevent mould growth, which allows the light bottle to last longer. The diagram on the last page, diagram 1, clearly explains how the solar light bottles are installed. Once the solar light bottle is installed, and the sun’s ray shines through the clear substance, which has a higher density, refraction occurs, which is the bending of light. When the process of refraction occurs, approximately fifty five watts-worth of light is evenly spread around the space where the light bottle is installed. The diagram on the last page, diagram 2, shows the process of
