Einstein: Genius Among Geniuses In March 1905 , Einstein created the quantum theory of light, the idea that light exists as tiny packets, or particles, which he called photons. Alongside Max Planck's work on quanta of heat Einstein proposed one of the most shocking idea in twentieth century physics: we live in a quantum universe, one built out of tiny, discrete chunks of energy and matter. Next, in April and May, Einstein published two papers.

Who Discovered Infrared Light? Infrared light was discovered in 1800 by Sir Frederick William Herschel. Herschel, born in Hanover, Germany, decided to investigate the temperature of each color of the spectrum produced when sunlight is passed through a prism.To do this, he used three thermometers whose bulbs he blacked out (the better to absorb heat with).erschel, born in Hanover, Germany, decided to investigate the temperature of each color of the spectrum produced when sunlight is passed through a prism.

The History of the Light Bulb In 1802, Sir Humphry Davy, an English physician, created the first electric light by passing a current through a platinum strip. The glow did not last long, but it marked the beginning of the history of light bulbs.

Ultraviolet Light-emitting diodes (LEDs) can be manufactured to emit light in the ultraviolet range, although practical LED arrays are very limited below 365 nm. LED efficiency at 365 nm is about 5–8%, whereas efficiency at 395 nm is closer to 20%, and power outputs at these longer UV wavelengths are also better.

- Sir Isaac Newton, held the theory that light was made up of tiny particles. In 1678, Dutch physicist, Christiaan Huygens, believed that light was made up of waves vibrating up and down perpendicular to the direction of the light travels, and therefore formulated a way of visualising wave propagation.

Solar Eclipses in History The second lightest and the second most abundant element known to humans was discovered independently by French astronomer Jules Janssen and British scientist Norman Lockyer during a Total Solar Eclipse on August 16, 1868. Because of this, it's named after the Greek word for the Sun - Helios.

Who Invented the Fluorescent Light? Peter Cooper Hewitt built upon the work of Julius Plucker and Heinrich Geissler, who applied electricity to tiny gas particles in a tube to create light. Hewitt created a bluish-green light with a mercury-filled tube. He teamed up with George Westinghouse to become the first team to manufacture it commercially. Thomas Edison applied for a patent in 1896, but his fluorescent light used X-rays to excite the atoms and never sold.

- Galileo 's originality as a scientist lay in his method of inquiry. First he reduced problems to a simple set of terms on the basis of everyday experience and common-sense logic.

- Uranus is the 7th planet in the Solar System, and the first planet discovered beyond the 5 planets that are visible with the unaided eye. So, who discovered Uranus?The discoverer was Sir William Herschel, who found it on March 13, 1781.Sir William Herschel. Even though Uranus is dim, it’s actually possible to see with the unaided eye in very dark, clear skies. But even so, nobody had ever officially recorded the movement of Uranus, so Herschel is the discoverer.ranus is the 7th planet in the Solar System, and the first planet discovered beyond the 5 planets that are visible with the unaided eye. So, who discovered Uranus?

- There were other experiments on incandescent light before  and after, but this was the first incandescent light bulb, as the  platinum filament was enclosed in a vacuum tube.    Sir Joseph Swann of England and Thomas Edison both developed  workable electric incandescent lamps during the 1870s.

Johann Ritter: The Discovery of Ultraviolet Light He studied refraction in lenses, and also carried out research on reflections from spherical and parabolic mirrors. His writings were the first to explain vision correctly, as a phenomenon of light coming into the eye, rather than the eye emitting light rays.

ultraviolet light ultraviolet light or ultraviolet radiation (UV) a type of electromagnetic radiation beyond the wavelength of visible violet light, ranging from 18,000 to 33,000 nm (see ELECTROMAGNETIC SPECTRUM). UV light is not an ionizing radiation like X-RAYS and can only penetrate a few cells.

- In the year 1800, William Herschel made another very important discovery. He was interested in learning how much heat passed through the different colored filters he used to observe the Sun and noticed that filters of different colors seemed to pass different levels of heat.

The Discovery of Electromagnetic Radiation Heinrich Hertz (1857-1894) on a German stamp featuring 100 years since his birth. The most dramatic prediction of Maxwell's theory of electromagnetism, published in 1865, was the existence of electromagnetic waves moving at the speed of light, and the conclusion that light itself was just such a wave. This challenged experimentalists to generate and detect electromagnetic radiation using some form of electrical apparatus.

LED (Light Emitting Diode) General LED technology has existed for over forty years. The first visible-spectrum light-emitting-diode was invented in 1962 by Nick Holonyak, Jr., who was working as a consulting scientist for General Electric at the time. However, several factors kept the technology from advancing into practical lighting usage.

Johann Ritter: The Discovery of Ultraviolet Light He published five books about optics, but only one book has survived to the modern era. This series of works was dedicated to the study of color, reflection, refraction, and mirrors of various shapes.

- Ultraviolet light is a continuous spectrum of invisible light, much like the colours of the rainbow are a continuous spectrum of visible light that gradually changes from red through to blue.

- The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson. British Antarctic scientists Farmin, Gardiner, and Shanklin discovered the a … ctual hole in the Ozone in 1984 and published their findings in Nature in May of 1985.

Newtonâs Reflectors The birth of the reflecting telescope gives astronomers options. Get to the root of it. Newton was a busy man. He was the first to identify and begin to understand gravity. He discovered that white light is made up of colors, and he was among the first to formulate the mathematical discipline of calculus. And in 1668 in England, he created a small but powerful telescope that didn’t suffer from chromatic aberration.

- Thomas Young's Double Slit Experiment. In 1801, an English physicist named Thomas Young performed an experiment that strongly inferred the wave-like nature of light. Because he believed that light was composed of waves, Young reasoned that some type of interaction would occur when two light waves met.

Do all normal light bulbs emit UV rays and radiation? Incandescent lights (the kind Edison invented) don't make much UV. They do use a lot of energy (compared to fluorescent), and over half of it comes out as heat. Nobody has invented a fluorescent light that gives out white light. They did have one that gave off UV.

Incandescent One of those people was British physicist Joseph Wilson Swan, who actually received the first patent for a complete incandescent light bulb with a carbon filament in 1879. Swan’s house was the first in the world to be lit by a light bulb.

- Photons were first postulated by Planck, whose measurements of the blackbody spectrum showed that electromagnetic radiation had to come in discrete units, which were dubbed photons by the chemist Gilbert Lewis in 1926 (Griffiths 1987, p. 15).
