Who invented the spectroscope and what were some of its first uses?
ROBERT WHILMEN BUSEN
Spectroscopes are often used in astronomy and some branches of chemistry. Early spectroscopes were simply prisms with graduations marking wavelengths of light. Modern spectroscopes, such as monochromators, generally use a diffraction grating, a movable slit, and some kind of photodetector, all automated and controlled by a computer. The spectroscope was invented by Joseph von Fraunhofer.
The wheel was revolutionary. Today, almost everything uses a wheel. No one knows why the wheel was invented, but I know that in Mesopotopia, in the year 3500BC, someone invented it and used it as what we call the "potter's wheel". Others believe that cave-men invented it before that; in the stone age. sumerians invented the wheel and used it for vehicals,sailboats,mechines,and pottery bowls.
Spectroscopes are used to determine the elements present in different substances. They do this by separating light into spectra, or different colors. Each element has a unique spectra, just like people each have a unique fingerprint. By looking at the light from a star, for example, a scientist can tell that it contains hydrogen, helium, and other elements. It was discovered that our sun contained helium by using a spectroscope during an eclipse- this was…
The metal element of Iron (Fe) was never "invented" as it has existed across the Universe for billions of years. That being said humanity is thought to have first exploited Fe for industrial and social uses some 3500+ years ago. Since the use of Fe has become an inseparable aspect to modernity through steels and other metal working. Although Fe was never invented, it was to be discovered, exploited and refined through human technology.
