What is the spectroscope and what did Gustav Robert Kirchhoff use it for?

Together Kirchhoff and Bunsen invented the spectroscope, which Kirchhoff used to pioneer the identification of the elements in the Sun, showing in 1859 that the Sun contains sodium. He and Bunsen discovered caesium and rubidium in 1861.

What did Gustav Kirchhoff discover?

Gustav Kirchhoff/Discovered

Is Kirchhoff a Russian name?

German: from Middle High German kirche ‘church’ + hof ‘court’, ‘yard’, hence a topographic name for someone dwelling near a churchyard or at a farm situated by a church or owned by the Church.

What is Loop rule formula?

Kirchhoff’s Loop Rule Formula. In any “loop” of a closed circuit, there can be any number of circuit elements, such as batteries and resistors. The sum of the voltage differences across all of these circuit elements must be zero. This is known as Kirchhoff’s Loop Rule.

What did Robert Bunsen and Gustav Kirchhoff do?

In addition to formulating laws of electrical currents and thermal radiation, Gustav Kirchhoff developed a spectroscope with Robert Bunsen, and the pair pioneered the field of analytical spectroscopy (the study of the emission and absorption of light and other radiation by matter in terms of their relationship to the wavelength of the radiation).

When did Robert Bunsen invent chemical spectroscopy?

A new science had been born – chemical spectroscopy. Using their newly invented method, Bunsen and Kirchhoff discovered two new elements: cesium in 1860, and rubidium in 1861. The beauty of spectroscopy is that tiny traces of a substance can be detected.

How did Kirchhoff and Bunsen discover the two new metals?

[p.409] Bunsen has communicated a preliminary notice of the two new metals discovered by Kirchhoff and himself by means of the spectral analysis. Both of these metals exhibit in their compounds an extraordinary resemblance to potassium, and cannot be distinguished from it either by reagents or by the blowpipe.

What did Robert Bunsen do at Heidelberg University?

In 1852, Bunsen took the Chair of Chemistry at Heidelberg University. In 1854, he arranged that his friend Kirchhoff should follow him, to take the Chair of Physics. The pair then formed a highly productive research partnership. Kirchhoff was interested in the new science of spectroscopy.
