Incandescent light bulbs have been such a hit that the original technology hasn’t undergone any drastic changes. It’s interesting to note that such a minute (but also critical!) part of our existence is based on important aspects of physics. In this article, we’ll find the answers to s...
The sun, stars, fire, candles, electric bulbs are all the examples of light sources. As they radiate light, they are said to be luminous. Light sources can be natural or artificial. 6.1 Natural light sources Amongst many light sources, the most common and natural light source is a simple...

Edison also undertook exhaustive experiments to improve the carbon filament, which was made from cotton thread, wood splints and papers. These experiments indicated that bamboo or similar fibrous material made the best filaments for incandescent light bulbs. In 1880, he hired William H. Moore, of ...

In more general terms, these results suggest that it is important that the developing child is exposed to white light, such as natural sun light (without blue light reducing filters) or artificial lighting that is rich in blue light (daylight bulbs). A light source containing blue, green and...
On the other hand, light bulbs existing prior to Edison’s efforts burned for a short time – the best achievement was Swan’s, 13.5 hours, though a great breakthrough, not commercially yet. Thomas Alva Edison, a prolific inventor, and his team (yes, he did not work alone!) experiment...
Was Albert Einstein born in the year electric light bulbs were invented? Did Thomas Edison write any books? What was the first thing Benjamin Franklin invented? What were Ben Franklin's contributions to the study of electricity? Who were Thomas Edison's siblings? Did Thomas Edison invent the ...
We know nothing; we have to creep by the light of experiments, never knowing the day or the hour that we shall find what we are after. Everything, anything is possible; the world is a vast storehouse of undiscovered energy. The recurrence of a phenomenon like Edison is not very likely...
