Who invented the hydrogen spectrum?

Theodore Lyman
The series is named after its discoverer, Theodore Lyman, who discovered the spectral lines from 1906–1914. All the wavelengths in the Lyman series are in the ultraviolet band.

Who explain the line spectrum of hydrogen?

Bohr’s model explains the spectral lines of the hydrogen atomic emission spectrum. While the electron of the atom remains in the ground state, its energy is unchanged. When the atom absorbs one or more quanta of energy, the electron moves from the ground state orbit to an excited state orbit that is further away.

Who predicted all of hydrogen’s emission lines?

To introduce the concept of absorption and emission line spectra and describe the Balmer equation to describe the visible lines of atomic hydrogen.

What background theory did JJ Balmer arrive to his formula?

Johann Jakob Balmer was a Swiss mathematician and mathematical physicist born on May 01, 1825 – died on March 12, 1898. Balmer was the discoverer of balmer formula. He discovered a formula basic to the development of atomic theory.

Who developed an empirical equation from which the wavelengths of lines in the spectrum of hydrogen atoms can be calculated?

Johann Balmer
An empirical formula to describe the positions (wavelengths) λ of the hydrogen emission lines in this series was discovered in 1885 by Johann Balmer. It is known as the Balmer formula: 1 λ = R H ( 1 2 2 − 1 n 2 ) . 1 λ = R H ( 1 2 2 − 1 n 2 ) .

What was Niels Bohr’s explanation for the observation of atomic spectra?

What was Niels Bohr’s explanation for the observation of atomic spectra? Electrons could only move in discrete energy steps within an atom. Only certain photons with the correct energy could excite the quanta in the nucleus.

When was Brackett invented?

1922
Brackett received a doctorate in physics from the Johns Hopkins University in 1922. Applying a hydrogen filled discharge tube, he discovered the hydrogen Brackett series, where an electron jumps up from or drops down to the fourth fundamental level, in 1922.

Who discovered Balmer series?

mathematician Johann Jakob Balmer
discovery by the Swiss mathematician Johann Jakob Balmer of a simple arithmetic formula relating the wavelengths of lines in the hydrogen spectrum (1885) proved to be the start of intense activity in precise wavelength measurements of all known elements and the search for general principles.

How does Bohr model explain the line spectrum of hydrogen?

Niels Bohr explained the line spectrum of the hydrogen atom by assuming that the electron moved in circular orbits and that orbits with only certain radii were allowed.

Which scientist first proposed that the electron in the hydrogen atom can have only certain energies?

In 1913, Niels Bohr proposed a theory for the hydrogen atom, based on quantum theory that some physical quantities only take discrete values.

What was the name of Democritus model?

This fundamental or basic unit was what Democritus called an atom. He called this the theory of the universe: All matter consists of atoms, which are bits of matter too small to be seen.

Who is Niels Bohr and what did he discover?

Niels Bohr proposed a model of the atom in which the electron was able to occupy only certain orbits around the nucleus. This atomic model was the first to use quantum theory, in that the electrons were limited to specific orbits around the nucleus. Bohr used his model to explain the spectral lines of hydrogen.

What is the longest wavelength in Brackett series?

1 Answer. The correct option is (c) 40519 Å. Explanation: For Brackett series.

How is the third line of Brackett series produced?

Answer: the Brackett Series for the emission spectra of hydrogen the final destination of a dropping electron from a higher orbit is n=4 . The third line of Brackett series is formed when electron drops from n=7 to n=4. The released wavelength lies in the Infra Red region of the spectrum.
